@aduth Why was this added? This seems to be causing the IE bug #20598.

@ellatrix If I recall correctly, the idea was that if this logic should not cause a change in focus, and there was no focused element before the selection applied, we should guarantee that there is no focused element after it's applied by calling
blur
on whichever element is focused at that point.I'm not able to remember if there was a specific case in mind this was addressing, or if it was only here to deal with the hypothetical technical possibility.
Based on the debugging information from the original pull request comment, I suspect the main fix for Trac#49519 is largely in adding the condition of
if ( activeElement ) {
(accounting for the fact thatactiveElement
can benull
). If that's enough to accommodate all of the current scenarios and fix both Trac#49519 and #20598, then maybe it would be fine to remove thisblur
call.
