Description:
http/tests/in-app-browser-privacy/top-frame-redirect-to-non-app-bound-domain-blocked.html

The first failure that I see this on the dashboard was 09/30/20 at r267785, 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 or earlier.
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.
