Found while fuzzing m-c 20230624-36c126e25c92 (--enable-debug --enable-fuzzing)

To reproduce via Grizzly Replay:

$ pip install fuzzfetch grizzly-framework
$ python -m fuzzfetch -d --fuzzing -n firefox
$ python -m grizzly.replay ./firefox/firefox testcase.html --repeat 25

Unfortunately the attached test case is not very reliable.
