Block URL in URLRequest errors prevent browsing to many common sites

[Slime90]

Describe the bug When browsing to many common websites, a "Block URL in URLRequest errors" message occurs and the page crashes

[15871:15914:1012/113635.764133:ERROR:url_request.cc(626)] Block URL in URLRequest: https://support.9oo91e.qjz9zk/chrome/?p=e_awsnap [15871:15914:1012/113635.764214:ERROR:trk_protocol_handler.cc(17)] Blocked URL in TrkProtocolHandler: trk:https://support.9oo91e.qjz9zk/chrome/?p=e_awsnap [15871:15914:1012/114036.624655

Expected behavior On the release version of ungoogled-chromium 74, and others I have used on non PPC platforms, this happens in the background and does not interrupt browsing.

Environment (please complete the following information):

• OS/Platform and version: Ubuntu 19.04 up to date, running on a Talos Blackbird
• ungoogled-chromium version: Version 77.0.3865.90 (Official Build) (64-bit)

@Slime90 This is ungoogled-chromium, not Chromium, lots of URLs pointing to Google are purposefully blocked. If you want to suggest changing this behavior, see this with upstream: https://github.com/Eloston/ungoogled-chromium

AFAICT this only happens if you manually click some of the built-in buttons that are intended to open Google Support URLs, not if you manually browse the site with the correct URL. This behavior does happen in non-PPC binaries too.
