ENABLE_OVERFLOW_SCROLLING is currently disabled in features.gypi (except for Android). We should turn it on by default if possible.
I rebaselined some tests with expectations pointing to this bug in r126734, I would appreciate it if you could sanity check me on the rebaselines.
This is a bit weird since the original baselines had the expected result when OVERFLOW_SCROLLING is on, but the new ones are generated with OVERFLOW_SCROLLING disabled. The former were meant as a golden sample against which composited scrolling could be verified.
I guess having baselines from non-standard build configurations isn't really sustainable, so let's keep the new ones for now and revisit once we can flip the switch for OVERFLOW_SCROLLING.
Looks like compositing/overflow/overflow-auto-with-touch-toggle.html is no longer failing either, for some reason.
Marked LayoutTest bugs, bugs with Chromium IDs, and some others as WontFix. Test failure bugs still are trackable via TestExpectations or disabled unit tests.
