4 tests in virtual/display_list_2d_canvas/fast/canvas are flaky when run in random order

Project Member Reported by qyears...@chromium.org, Nov 14 2016

Issue description

The tests:

virtual/display_list_2d_canvas/fast/canvas/canvas-createImageBitmap-webgl.html
virtual/display_list_2d_canvas/fast/canvas/canvas-drawImage-live-video.html
virtual/display_list_2d_canvas/fast/canvas/OffscreenCanvas-2d-drawImage.html
virtual/display_list_2d_canvas/fast/canvas/OffscreenCanvas-commit-invalid-call.html

appear to be flaky when run in random order. Steps to reproduce:

This should pass consistently:
Tools/Scripts/run-webkit-tests virtual/display_list_2d_canvas/fast/canvas

This should fail intermittently:
Tools/Scripts/run-webkit-tests virtual/display_list_2d_canvas/fast/canvas --order=random

We're working on removing order dependency from Blink layout tests. More context here:

Remove flaky expectations with update-test-expectations script

The update-test-expectations script is meant to remove
flaky expectations when it appears that according to the
most recent results on the flakiness dashboard for that test,
the test is no longer flaky.

Comments regarding this bug being fixed are wrong. The tests are still flaky.

Display list 2d mode is already removed in https://bugs.chromium.org/p/chromium/issues/detail?id=776826.

So this issue is no longer relevant.
