The HTML spec changed recently to remove the CG-derived radius hack. Mozilla now conform to the spec, and we should too. See

Do you have an example file? Do we even want to fix it?

Test case from Mozilla Bug - https://dbaron.org/css/test/2010/shadow-blur

Safari 15.5 on macOS 12.4 matches other browsers like Chrome Canary 104 and Firefox Nightly 103 in the above and if it is related to this bug as per Comment 01 then it is fixed IMO.

If I am testing wrong or this is about something else. Please ignore. Thanks!

Current rendering looks nothing like what the explanatory text says it should be ("should match Tab's demo with sigma=50"), so leaving to Simon to decide if we are good now.
