> [Chromium] Modify Android's user agent CSS to not set a border-radius on select elements
> https://bugs.webkit.org/show_bug.cgi?id=106327
> 
> Reviewed by Adam Barth.
> 
> Android's user agent CSS overrides the style applied to <select>
> elements with a @size or @multiple attribute, and then applies
> (among other things) a border-radius of 5 pixels. While select
> elements with a larger size or multiple selection should appear
> as drop-down boxes for now, setting the border radius causes
> Chromium to skip rendering the background and border, making
> them hard to read when the page relies on the default styling.
> 
> This is covered by existing pixel tests.
