Various ExtensionsInstalledBubbleBrowserTest tests fail:
ExtensionInstalledBubbleBrowserTest.InvokeUi_PageAction

I think this is a real memory bug. ASan gives a relatively understandable UAF report:

Please take a look. We should disable these tests. These tests always fail with Windows ASan, but without ASan, they will be flaky.
