Description Ryosuke Niwa 2014-02-14 01:02:31 PST
HTMLTextFormControl::setSelectionRange doesn't need to trigger a synchronous layout
if the text field is already focused since we don't need to call hasVisibleTextArea in that case,
which depends on the dimension of RenderBox.

We can get rid of synchronous layout completely once we fix webkit.org/b/38696 as I've outlined in

but we can fix this one first in order to resolve the bug 128797 since we don't call setSelectionRange in setValue when the text field is not focused.

Odd. I thought I removed this tab character before uploading it :/
