Steps to reproduce

To reproduce, open the attached test case, focus the editor, type the letter “a,” and then press the Return key three times. The browser tab crashes on the third Return.

This test case uses the Trix editor. I have not yet distilled a more minimal test case without the Trix dependency, but I suspect the issue may be related to Trix’s rendering inside its own MutationObserver callback as a result of the above key sequence.
