DumpAccessibilityTreeTest.AccessibilityModalDialogInIframeClosed is failing on Win8 Aura

Project Member Reported by alex...@chromium.org, Mar 10 2016

Issue description

This started failing in https://build.chromium.org/p/chromium.win/builders/Win8%20Aura/builds/37637

Strangely, despite the bot name, it's failing as part of the "content_browsertests on Windows-7-SP1" step.

Output:

This is most likely caused by https://codereview.chromium.org/1761633002, so assigning to dmazzoni@. I'll go ahead and disable this for Windows for now.

It appears that it's actually flaky.  The next two builds succeeded before the test was disabled: https://build.chromium.org/p/chromium.win/builders/Win8%20Aura/builds/37639 and https://build.chromium.org/p/chromium.win/builders/Win8%20Aura/builds/37640

However, it appears that DumpAccessibilityTreeTest.AccessibilityModalDialogInIframeOpened is similarly flaky.  It just failed on https://build.chromium.org/p/chromium.win/builders/Win7%20Tests%20%281%29/builds/49739:

This appears flaky just like AccessibilityModalDialogClosed which was
disabled earlier.

Has anyone at Google seen this test flake on any of your Android testers?

Particularly AccessibilityModalDialogInIframeClosed seems to flake a lot on some of our Android testers - from what I can tell with the same trace as those posted above:
