The patch looks OK, but it looks like some other part of the code is depending on this style resolution.  We'll need to debug that layout test failure.

Yep, looks like setAttribute('style', '-webkit-appearance: none') works for this today, but .style.webkitAppearance = 'none' does not. Crazy. CC'ing morrita who added the test.

Let's try this again, as I can't reproduce the failure anymore. I suspect that something got fixed in shadow DOM styling over the last 9 months and this now works as it should.. *fingers crossed for ews*
