MimeHandlerViewTest.Iframe and SmartSessionRestoreTest.CorrectLoadingOrder are failing in single_process_mash_browser_tests on linux-chromeos-dbg

Project Member Reported by afakhry@chromium.org, Jan 17 (5 days ago)

Issue description

Most recent failures: https://ci.chromium.org/p/chromium/builders/luci.chromium.ci/linux-chromeos-dbg/10320

They both have been failing for a few builds since yesterday. SmartSessionRestoreTest.CorrectLoadingOrder appears to be flaky, while MimeHandlerViewTest.Iframe seems to be reliably failing.

FindIt couldn't find a culprit CL.

James, we already have an entry to exclude SmartSessionRestoreTest.* in chromeos.mash.fyi.browser_tests.filter https://cs.chromium.org/chromium/src/testing/buildbot/filters/chromeos.mash.fyi.browser_tests.filter?type=cs&q=SmartSessionRestoreTest&sq=package:chromium&g=0&l=114
Not sure if that builder honors that file.

chromeos.mash.fyi filters are for the full out-of-process mash case, not SingleProcessMash, so this test suite doesn't use them.

Comment 2 by afakhry@chromium.org, Jan 17 (5 days ago)

James, should we disable these tests? Is there a corresponding filter for single process mash?

 Issue 922987  has been merged into this issue.

MimeHandlerViewTest.Iframe fails on ASAN too.

We no longer use a filter file for single process mash since we plan to turn it on by default. For now, we have to disable it in code and make sure to have a tracking bug.
e.g.

  // TODO(https://crbug.com/923051): Flaky in single process mash.
  if (features::IsSingleProcessMash())
    return;

Thanks, xiyuan!

[single_process_mash_browser_tests] SmartSessionRestoreTest.CorrectLoadingOrder

is also flaky now.

Opps that's the same test from before. Sorry.
