REGRESSION(311766@main): Textareas can get unnecessary horizontal scrollbar.
https://bugs.webkit.org/show_bug.cgi?id=314412
rdar://problem/176566654
Reviewed by Alan Baradlay.
When a renderer begins tracking scrollbar changes in its descendants, it
is possible for textareas to get an unnecessary horizontal scrollbar if
it is one of those descendants. From an initial investigation this seems
to come from the fact that the renderers associated text areas have
slightly different logic for comes their logical width when compared to
other renderers. While we gather more information to figure out what is
going on and what the proper fix is we should just disable this
functionality for textareas.
