This test is failing fairly often on Site Isolation Android.  For example: https://build.chromium.org/p/chromium.fyi/builders/Site%20Isolation%20Android/builds/2981

It's also flaky on other platforms:
https://test-results.appspot.com/dashboards/flakiness_dashboard.html#testType=content_browsertests&tests=NavigationControllerBrowserTest.ReloadWithUrlAnchor

Failure output:

../../content/browser/frame_host/navigation_controller_impl_browsertest.cc:1354: Failure
Value of: value
  Actual: 0
Expected: 100

Assigning to chaopeng@, who added the test in https://codereview.chromium.org/2541513004.  I'll probably disable it for now to keep the bots green.
