rememberthemilk.com: REGRESSION (280692@main): Clicking on the dropdown list
doesn't expand to display its content
https://bugs.webkit.org/show_bug.cgi?id=280787
rdar://136259655
Reviewed by Alan Baradlay.
The page uses attribute selectors that query the value of the style attribute
[style*="display: none;"].b-FS-n { display: block; … }
With the optimization implemented in 280692@main we fail to invalidate
correctly when the
inline style is programmatically mutated, affecting the value of the style
attribute.
