Bug 167216 – Remove synchronous layout in HTMLTextFormControlElement::setSelectionRange

• Component: WebCore Misc.
• Status: RESOLVED LATER

[Brent Fulgham]

While working on an unrelated bug, I noticed that an extra layout was being performed. This layout had been added as a workaround Bug 128797, which is now fixed.

Rather than perform an unneeded synchronous layout, let's remove it!

Nope! Looks like this won't work.

Removing the workaround Ryosuke mentioned is not safe (yet).

FIXME comment was updated in r224296 but I'm not sure there is a new bug for that.

[Ryosuke Niwa]

We need to do more work before we can remove the sync layout there.
