[Paint Preview] Re-enable overscroll test

This test was disabled due to an M85 bot on failing. However, the tests
were drastically refactored for M86. I don't think this is still an
issue with the refactored tests as the crash location no longer exists.
See comments on bug for more details on why I think a simple enable
should suffice.

Will monitor for new flakes over the next few days.
