Navigation-related browser tests are flaky on Win 7 bots

Project Member Reported by chromium...@appspot.gserviceaccount.com, Aug 8 
"NavigationControllerBrowserTest.BackToAboutBlankIframe" is flaky.

This issue was created automatically by the chromium-try-flakes app. Please find the right owner to fix the respective test/step and assign this issue to them. If the step/test is infrastructure-related, please add Infra-Troopers label and change issue status to Untriaged. When done, please remove the issue from Sheriff Bug Queue by removing the Sheriff-Chromium label.

We have detected 3 recent flakes. List of all flakes can be found at https://chromium-try-flakes.appspot.com/all_flake_occurrences?key=ahVzfmNocm9taXVtLXRyeS1mbGFrZXNyQQsSBUZsYWtlIjZOYXZpZ2F0aW9uQ29udHJvbGxlckJyb3dzZXJUZXN0LkJhY2tUb0Fib3V0QmxhbmtJZnJhbWUM.

Flaky tests should be disabled within 30 minutes unless culprit CL is found and reverted. Please see more details here: https://sites.google.com/a/chromium.org/dev/developers/tree-sheriffs/sheriffing-bug-queues#triaging-auto-filed-flakiness-bugs

Lots of NavigationControllerBrowserTests are flaking, so grouping all under one bug:

NavigationControllerBrowserTest.BackToAboutBlankIframe
NavigationControllerBrowserTest.FrameNavigationEntry_BackNestedAutoSubframe
NavigationControllerBrowserTest.FrameNavigationEntry_BackWithRedirect
NavigationControllerBrowserTest.NavigationTypeClassification_NewAndAutoSubframe
NavigationControllerBrowserTest.NavigationTypeClassification_On1SameDocumentToXWhile1Pending

Labels: OS-Windows
Summary: NavigationControllerBrowserTest.* are flaky on win7_chromium_rel_ng (was: "NavigationControllerBrowserTest.BackToAboutBlankIframe" is flaky)
Earliest run showing flakes in any of these tests is https://build.chromium.org/p/tryserver.chromium.win/builders/win7_chromium_rel_ng/builds/53805 .

Comment 9 by pkasting@chromium.org, Aug 10 

That build picked up r580473, so if this isn't bot issues, the implication is something at that CL or earlier.

CCing folks who landed changes around the time this started having problems

Comment 13 by pkasting@chromium.org, Aug 10 

This has now taken as much sheriffing time as I can spare on it for the moment.  Hoping some navigation folks can pick this up.  If not the next step is to mass-disable all NavigationControllerBrowserTest.* tests, which I'd rather avoid.

Comment 14 by pkasting@chromium.org, Aug 10

Summary: Navigation-related browser tests are flaky on Win 7 bots (was: NavigationControllerBrowserTest.* are flaky on win7_chromium_rel_ng)
A lot of navigation tests are flaky on Win 7 debug too.  For example, in https://ci.chromium.org/p/chromium/builders/luci.chromium.ci/Win7%20Tests%20%28dbg%29%281%29/70804 , we had the following failures:

NavigationHandleImplBrowserTest.VerifySameDocument
BrowserSideNavigationBrowserTest.IframeAndPushStateSimultaneously
NavigationControllerBrowserTest.EnsureSamePageNavigationUpdatesFrameNavigationEntry
NavigationHandleImplBrowserTest.VerifyRendererInitiated
NavigationControllerBrowserTest.SubframeBackFromReplaceState

This looks like more than just NavigationControllerBrowserTest.*; it's some sort of general navigation-related issue, and it's affecting multiple bots over a long period.  Something real is wrong.

Looking at when this started failing, this may be related to http://crrev.com/b7e7131

CCing Nick to see if he thinks it could be related.

+palmer@, as I see "Throttling history state changes to prevent the browser from hanging" in #c10 followed by test failures when the test doesn't find the expected history entries.

Chances are good this is a duplicate of  issue 870861  (which is on my plate, as #16 notes), although un-dup it if I'm wrong.
