I can't speak to the prioritization differences between the different browser teams, Chrome was definitely the best which isn't surprising considering their resources. Apple was also quite swift but I imagine it took them some time to decide where to deliver the fix, I myself wasn't sure if this is something that should be blocked at the OS level (the Authentication checking the intent origin) or browser. Mozilla is usually the slowest out of the three but they were still very professional.
