Previously, when project search results first appeared, vim would
incorrectly switch to Visual mode. This happened because vim settings
(including `collapse_matches`) weren't synced to an editor until it
received focus. Since the results editor wasn't focused when the first
match was selected, the selection wasn't collapsed, causing vim to
interpret it as a visual selection.

Now vim settings are synced immediately when vim activates on an editor,
ensuring `collapse_matches` is set before any selections are made.

Closes #43878

Release Notes:

- Fixed vim mode incorrectly switching to Visual mode on first project
search
