Description Alexey Proskuryakov 2015-01-23 22:12:10 PST
fast/html/marquee-scrollamount.html frequently fails on Yosemite Debug WK2.

Looking at the test, it is inherently flaky. Some non-trivial time can pass before the zero delay timer fires, and nothing prevents the marquee from updating its position.

Except it looks like it needs some test results cleanup.

I can fix the test more reliably, but this depends on fixing an actual bug in HTMLMarqueeElement.

Not marking for review yet, because this depends on another patch, and EWS wouldn't be testing the right thing.
