FWIW, I am not encountering any freezes playing the tiles game on Safari Technology Preview Release 104 (Safari 13.2, WebKit 15610.1.8.3) or Firefox 74.0.
Within minutes of posting that a Safari Technology Preview update was announced. It is now Release 105 (Safari 13.2, WebKit 15610.1.10)

If we knew what it was we were doing, it wouldn't be called research, would it?
