[GTK] 3 Layout Test at fast/regions/repaint/region-painting-* crashes sometimes.

[Carlos Alberto Lopez Perez]

The following layout test is flaky (crashes sometimes) on platform GTK

fast/regions/repaint/region-painting-composited-element.html

[Carlos Alberto Lopez Perez]

The test fast/regions/repaint/region-painting-in-composited-view.html shows the same behavior (crashes sometimes)

[Carlos Alberto Lopez Perez]

Also the test fast/regions/repaint/region-painting-invalidation.html crashes sometimes.

The issue don't seems easy to reproduce. I have been running the tests in a loop and i was unable to cause the crash. However they crash on the bots from time to time so I'm marking this 3 tests as flaky on the test expectations.

Crash for fast/regions/repaint/region-painting-in-composited-view.html

Finally I was able to reproduce the crash on one of them by running all the 3 tests in a loop until one crashed. I'm attaching the GDB backtrace for the crash for fast/regions/repaint/region-painting-in-composited-view.html

I have added this test to the list of expected failures for GTK on https://trac.webkit.org/r172017. Please remove it from the list if you fix the issue. Thanks
