Since nightly and release are affected, beta will likely be affected too.

The site specifies vendor-specific pseudo elements in CSS as follows.

This was just a filename mis-match which I accidentally missed by not running this test one last time before landing. I'm landing again with that one change to match the filename in interventions.json (the test now passes for me locally, so it ought to be fine).
