[549/549] OmniboxViewTest.ClearUserTextAfterBackgroundCommit (CRASHED)
========

First failure of this kind seems to be

https://ci.chromium.org/p/chromium/builders/luci.chromium.ci/Mac10.10%20Tests/31940

Overall it failed 7 times afterwards, the latest one is https://ci.chromium.org/p/chromium/builders/luci.chromium.ci/Mac10.10%20Tests/31994.

I don't see anything related in 31940,

there is https://chromium-review.googlesource.com/c/chromium/src/+/1047666 "Componentize OmniboxController unittest" in 31939, but it is likely unrelated.

there is nothing suspicious in 31938 either, so disabling the test.

The CL is https://chromium-review.googlesource.com/c/chromium/src/+/1051648.

Please have a look and potentially reassign.

Re-enable disabled tests in chrome/browser/ui/omnibox/.

These passed 50 times in a row on Windows.

This converts from watching NOTIFICATION_NAV_ENTRY_COMMIT to using a navigation
observer in hopes of fixing observed flakiness in EnterToSearch.

Glad that one is no longer flaky.

As they flake we can incrementally convert them to unit tests. I updated 751031 to be a tracking bug for that incremental conversion work.
