[webkit-dev] Call For Help: Media controls layout issue

I've been knee deep trying to debug this chromium issue
http://crbug.com/74826 that I believe is not port specific and may be
related to https://bugs.webkit.org/show_bug.cgi?id=49023.

Basically, the timeline slider control is being painted fine and the correct
rect is hitting the theme, but copious debugging reveals that mouse down
events never reach the control, but instead are fired on it's parent

It is as though the RenderSlider always has it's default desired width as
far as hittesting is concerned.

For background, the slider and it's parent are flexible boxes. If I modify
the ua style to remove "-webkit-appearance: media-slide" (changed to none)
and the height (changed to auto), the correct behaviour occurs, but if
either (or both) of them are changed back, the problem re-occurs.

Any help or insight appreciated - I've created bug
https://bugs.webkit.org/show_bug.cgi?id=59644, if we wish to take the
discussion there.
