Problem
Sometimes Caret disappears on mobile devices:
IMG_4707.MP4
Cause
Problem located in
caret.setToBlock(). We're setting caret usingsetTimeoutand browser is blocking this action because it's prohibited to programmatically set a caret without user action. So it's not working inside a setTimeout callback.Solution
I tried to change setTimeout with
requestAnimationFrameit also seems working. But then I tried to remove timeout at all. And looks like nothing breaks, so it looks like a legacy.Resolves #2406
Resolves #2287 (possible)
