On STP 152

The corners toggle between rounded and square corners during the animation. This does not happen in Chrome or Firefox.

Confirmed. Here a reduced test case.

Both Gecko and Blink make the transition without resetting the border-radius.
WebKit seems to reset the border-radius at the beginning of the transition, then reapply the border-radius.

I am unable to reproduce this bug in Safari Technology Preview 161 while it is reproducible in Safari 16.2.

Marking this as "RESOLVED CONFIGURATION CHANGED". Please reopen, if it is still reproducible. Thanks!

Confirmed it doesn't repro in STP 161.
