Description Alexey Proskuryakov 2015-07-25 18:38:05 PDT

These tests are very flaky on all Mac WK2 bots:

platform/mac-wk2/tiled-drawing/scrolling/frames/frameset-frame-scrollability.html
platform/mac-wk2/tiled-drawing/scrolling/frames/frameset-nested-frame-scrollability.html

Possibly started with <http://trac.webkit.org/r170270>, which added one of these tests. Diff go like this:

Added expectations in http://trac.webkit.org/r187396.

We already had bugs about that: bug 139901, bug 136554.

Not sure how I could possibly see them fail, given that we had the expectations. Strange.
