This issue is ongoing, just wanted to note that if you Allow ads/tracers in Shields the site will load and display as intended.

Just ran into this during webcompat checks, its problem is how we handle the request to sb.scorecardresearch.com/beacon.js. If we allow, it's fine. If I block it from devtools so that it's "properly" blocked, it's fine again. But the 307 to the empty data URL causes it to go into an infinite loop somehow (didn't dig that far down yet). Not sure if the 200 with empty response would be any better as it'd still think it managed to load it, realize it's bad for some reason, and retry.

Wanted to flag this because it's still an easily reproducible issue on all Brave channels (Release channel at v0.64.77 at the time of writing this).

Very high traffic/popular site and its worth moving this up in priority/getting eyes on it sooner rather than later. cc @rebron

edit: also wanted to highlight this users findings when troubleshooting:

Okay, this has required a bit of work to debug, but I believe it has to do with scorecardresearch.com.

Technically the filter /beacon.js should be blocking this. But its not. If the domain scorecardresearch.com is blocked outright it let the site render correctly.
