Description:
http/tests/in-app-browser-privacy/non-app-bound-domain-does-not-get-app-bound-session.html

The first failure after a series of constant passes that I see this on the dashboard was 09/29/20 at 267768, but does not appear to be relevant to what would have caused this.

I can reproduce this on r267763, but unable to reproduce on r267762.
Commit r267763 has to do with moving things on WebProcessPool associated with NetworkProcessProxy ownership and moves them
to WebsiteDataStore, which could have introduced the constant failure.  The change was introduced here https://trac.webkit.org/changeset/267763/webkit.

I think this should come before RELEASE_ASSERT(!m_hasSetApplicationBundleIdentifier). Otherwise it doesn't make sense. m_hasSetApplicationBundleIdentifier is set to false when the bundle ID is cleared.

I think this looks good as long as EWS is happy.

[Alex Christensen]

This didn't fix it in my release build.  Needs more investigation, but it is just a test infrastructure issue with the override bundle identifier, which is only used for tests.  We are now creating the network process before setting the override bundle identifier, which causes the assertion and test failures.  The solution is to set the test override bundle id earlier.

Thanks for fixing this, and making these tests more robust in the process.

We should probably remove this entry from WebPreferencesDebug.yaml now that it is unused.

Wait! I'd like to use it for some debug logging we were thinking about.

Actually, on second thought let's go ahead and remove all this. We can use a specific preference flag to trigger logging without needing to keep all of this cruft around. r=me
