Currently, STP (105) crashes when in TweetDeck, https://tweetdeck.twitter.com, when logged in and typing an emoji from the macOS emoji keyboard in any text input (or at least whether that's authoring a new tweet, replying to an existing one, or searching). It does _not_ crash if you paste an emoji into the same text field.
Could you please attach a crash log? I do not have an account.

Crash under WebCore::AsyncScrollingCoordinator::scheduleUpdateScrollPositionAfterAsyncScroll.
Sam, do you know if this is a recent regression? What happens in the system Safari version? Which OS version is this?
Based on the crash log, this is a duplicate of bug 210570, fixed in trunk bot not in STP yet. *** This bug has been marked as a duplicate of bug 210570 ***
