Subject: [PATCH] [ML] Single Metric Viewer: Fix brush update on short recent
 timespans. (#56125)

Fixes an issue where the context chart brush would render incorrectly for short recent time spans (e.g. 'now-15min`). Adds a check whether to display the brush and hide it if context and focus chart have the same timespan.
