Updating to 2027.7 Broke Custom Cards for me and I can't fix them

Even a rollback of my docker image to 2026.6 did not fix this which is driving me insane.

The cards are working fine in the app but not on my desktop browser with firefox

Weirdly the cards appear perfectly fine in the Android app though which is very confusing
