Created attachment 377118 [details] Source of page with bug Bug occurred on: 12.1.2 (14607.3.9) on MacOS 10.14 Screencast with problem: https://www.loom.com/share/53f2c217235548e68af62426b14ec0b8 Buggy select dropdown has webkit-appearance in style, clicking on it causes the page to crash and then refresh. Expected result: select dropdown menu appears.
This is no longer crashing for me on Safari 13 on macOS 10.15.
Ditto, and the website doesn't crash either. Marking as Configuration Changed.
