Comment 2 Bri Harris 2023-06-13 15:55:32 PDT

I was able to replicate this failure at ToT as follows:

run-webkit-tests --ios-simulator --root fast/text/basic/generic-family-reset.html --force

There were expectations on this test but no bug prior to this. I am attempting to replicate now on an Intel machine to verify both diffs are the same and attempt a re-baseline.
