+ * Calendar grid supports two mechanisms of keyboard navigation:

+ * The implementation largely follows the w3 example (https://www.w3.org/WAI/ARIA/apg/example-index/dialog-modal/datepicker-dialog) and shares the following issues:
+ * - (table navigation) Chrome+VO - weekday is announced twice when navigating to the calendar's header;
+ * - (table navigation) Safari+VO - "dimmed" state is announced twice;
+ * - (table navigation) Firefox/Chrome+NVDA - cannot use table navigation if any cell has a focus;
+ * - (keyboard navigation) Firefox+NVDA - every day is announced as "not selected";
+ * - (keyboard navigation) Safari/Chrome+VO - weekdays are not announced;
+ * - (keyboard navigation) Safari/Chrome+VO - days are not announced as interactive (clickable or selectable);
+ * - (keyboard navigation) Safari/Chrome+VO - day announcements are not interruptive and can be missed if navigating fast.

-/**
- * Calendar grid supports two mechanisms of keyboard navigation:
- * - Native screen-reader table navigation (semantic table markup);
- * - Keyboard arrow-keys navigation (a custom key-down handler).
- *
- * The implementation largely follows the w3 example (https://www.w3.org/WAI/ARIA/apg/example-index/dialog-modal/datepicker-dialog) and shares the following issues:
- * - (table navigation) Chrome+VO - weekday is announced twice when navigating to the calendar's header;
- * - (table navigation) Safari+VO - "dimmed" state is announced twice;
- * - (table navigation) Firefox/Chrome+NVDA - cannot use table navigation if any cell has a focus;
- * - (keyboard navigation) Firefox+NVDA - every day is announced as "not selected";
- * - (keyboard navigation) Safari/Chrome+VO - weekdays are not announced;
- * - (keyboard navigation) Safari/Chrome+VO - days are not announced as interactive (clickable or selectable);
- * - (keyboard navigation) Safari/Chrome+VO - day announcements are not interruptive and can be missed if navigating fast.

+ * - Keyboard arrow-keys navigation (a custom key-down handler).
+ *
+ * The implementation largely follows the w3 example (https://www.w3.org/WAI/ARIA/apg/example-index/dialog-modal/datepicker-dialog) and shares the following issues:
+ * - (table navigation) Chrome+VO - weekday is announced twice when navigating to the calendar's header;
+ * - (table navigation) Safari+VO - "dimmed" state is announced twice;
+ * - (table navigation) Firefox/Chrome+NVDA - cannot use table navigation if any cell has a focus;
+ * - (keyboard navigation) Firefox+NVDA - every day is announced as "not selected";
+ * - (keyboard navigation) Safari/Chrome+VO - weekdays are not announced;
+ * - (keyboard navigation) Safari/Chrome+VO - days are not announced as interactive (clickable or selectable);
+ * - (keyboard navigation) Safari/Chrome+VO - day announcements are not interruptive and can be missed if navigating fast.

+/**
+ * Calendar grid supports two mechanisms of keyboard navigation:
+ * - Native screen-reader table navigation (semantic table markup);
+ * - Keyboard arrow-keys navigation (a custom key-down handler).
+ *
+ * The implementation largely follows the w3 example (https://www.w3.org/WAI/ARIA/apg/example-index/dialog-modal/datepicker-dialog) and shares the following issues:
+ * - (table navigation) Chrome+VO - weekday is announced twice when navigating to the calendar's header;
+ * - (table navigation) Safari+VO - "dimmed" state is announced twice;
+ * - (table navigation) Firefox/Chrome+NVDA - cannot use table navigation if any cell has a focus;
+ * - (keyboard navigation) Firefox+NVDA - every day is announced as "not selected";
+ * - (keyboard navigation) Safari/Chrome+VO - weekdays are not announced;
+ * - (keyboard navigation) Safari/Chrome+VO - days are not announced as interactive (clickable or selectable);
+ * - (keyboard navigation) Safari/Chrome+VO - day announcements are not interruptive and can be missed if navigating fast.

-/**
- * Calendar grid supports two mechanisms of keyboard navigation:
- * - Native screen-reader table navigation (semantic table markup);
- * - Keyboard arrow-keys navigation (a custom key-down handler).
- *
- * The implementation largely follows the w3 example (https://www.w3.org/WAI/ARIA/apg/example-index/dialog-modal/datepicker-dialog) and shares the following issues:
- * - (table navigation) Chrome+VO - weekday is announced twice when navigating to the calendar's header;
- * - (table navigation) Safari+VO - "dimmed" state is announced twice;
- * - (table navigation) Firefox/Chrome+NVDA - cannot use table navigation if any cell has a focus;
- * - (keyboard navigation) Firefox+NVDA - every day is announced as "not selected";
- * - (keyboard navigation) Safari/Chrome+VO - weekdays are not announced;
- * - (keyboard navigation) Safari/Chrome+VO - days are not announced as interactive (clickable or selectable);
- * - (keyboard navigation) Safari/Chrome+VO - day announcements are not interruptive and can be missed if navigating fast.

-/**
- * Calendar grid supports two mechanisms of keyboard navigation:
- * - Native screen-reader table navigation (semantic table markup);
- * - Keyboard arrow-keys navigation (a custom key-down handler).
- *
- * The implementation largely follows the w3 example (https://www.w3.org/WAI/ARIA/apg/example-index/dialog-modal/datepicker-dialog) and shares the following issues:
- * - (table navigation) Chrome+VO - weekday is announced twice when navigating to the calendar's header;
- * - (table navigation) Safari+VO - "dimmed" state is announced twice;
- * - (table navigation) Firefox/Chrome+NVDA - cannot use table navigation if any cell has a focus;
- * - (keyboard navigation) Firefox+NVDA - every day is announced as "not selected";
- * - (keyboard navigation) Safari/Chrome+VO - weekdays are not announced;
- * - (keyboard navigation) Safari/Chrome+VO - days are not announced as interactive (clickable or selectable);
- * - (keyboard navigation) Safari/Chrome+VO - day announcements are not interruptive and can be missed if navigating fast.
