Regex multiline search broken

[RickStrahl]

Describe the bug

Whenever you type a \ into the find dialog it turns the search expression red and disable the search nav buttons.

Happens in plain mode as well as regex. As soon as you type the \ the dialog appears to show an error and becomes non-selectable. Looks like in regEx mode the count is still accurate if you add a valid regEx escape sequence.

Update: the regex multiline search \n is confirmed to be broken.

Expected Behavior

Dialog not to show in error mode.

Current Behavior

Shows in red error mode.

Reproduction Steps

Kitchen sink - default page.

Ctrl-F
Type a search expression that includes a slash

Red means that there are no matches, it also shows 0 of 0 below. In the screenshot there are no matches because the regex is invalid, and in text mode it should be red unless there is \ in the text

Ok, you're right - I misread that.

But with regex this happens:

Not it says 0 of 1 (which is wrong on both counts in this case: There should be more than 1 match and it's showing red even though it thinks there's a match)

Maybe I'm missing something about regEx search in the find because none of the \ escape sequences are working.

\t does find tabs for me.

But I can confirm that regex multiline search with \n does not work.
