Note: The actual edited comment in the bug view page will always show the original commenter’s name and original timestamp.

Testcase found while fuzzing mozilla-central rev d49f009b89ad (built with: --enable-address-sanitizer --enable-fuzzing).

Testcase can be reproduced using the following commands:
```
$ pip install fuzzfetch grizzly-framework
$ python -m fuzzfetch --build d49f009b89ad --asan --fuzzing -n firefox
$ python -m grizzly.replay ./firefox/firefox testcase.html
```
