Enable WebNavigationApiTest.UserAction test.

There have been various fixes in navigation code that have helped deflake
webNavigationApi tests. The goal of this CL is to enable the
WebNavigationApiTest.UserAction test and see if it has benefited from
these fixes and is no longer flaky.

 Issue 868921  has been merged into this issue.

In this latest iteration of trying to enable it, it fails with difference in source process id. I think I have an idea of what might be causing it and will put up a CL with change for this in a bit.

Author: Nasko Oskov <nasko@chromium.org>

Update WebNavigationApiTest.UserAction to wait for navigation.

The WebNavigationApiTest.UserAction loads a page with has a subframe in
a different site than the main frame. Since the main page is an
extension URL, those will get isolated in separate processes.
The test checks that a context menu in the subframe, which opens a link
in a new tab results in the correct event for the webNavigation API.
However, since it doesn't wait for the subframe navigation to complete,
the context menu creation can incorrectly capture the parent process id
instead of the subframe process id. This is timing dependent, which
leads to flakiness in the test. This CL adds an explicit observer
for the subframe navigation and updates the test expectation to reflect
the fact that the subframe is in a separate process than the parent.

This message was posted automatically by the chromium-try-flakes app. Since flakiness is ongoing, the issue was moved back into Sheriff Bug Queue (unless already there).

I will put up a patch to disable the test on Windows instead of reverting the patch in c#13, which adds an improvement to the test and improves its non-flakiness on other platforms.
