Reproduced the issue with Firefox 124.0a1 Bof Asan build [(366005a91eda)](https://treeherder.mozilla.org/jobs?repo=mozilla-central&revision=366005a91eda9c0b765207a0623b7a9e46d9dea8&selectedTaskRun=BvXiTu79T9e7DkbTzhIRGA.0) on Ubuntu 22 by visiting the website from comment 0 and by opening the test case from comment 12 with the `export GNOME_ACCESSIBILITY=1` env variable set. A tab crash can be seen. Running the test case will crash the tab with and without the environment variable as stated in comment 12.

Verified fixed with Firefox Asan Bof 124.0a1 (2024-02-13), Firefox 123.0 (20240212203859) AsanBof and Firefox 115.8.0esr (20240213011312) AsanBof on Ubuntu 22. This was tested by accessing the webpage mentioned in comment 0 along with the test case, and then using the Tab key to focus on the red box, with the `export GNOME_ACCESSIBILITY=1` environment variable enabled and without it.

I have also tested Firefox Asan Bof 124.0a1 (2024-02-13), and Firefox 123.0 (20240212203859) Asan Bof on Windows 10x64 by using the test case and the link from comment 0, and no tab crashes can be seen. Note that Firefox [115.8.0esr Asan Bof](https://treeherder.mozilla.org/jobs?repo=mozilla-esr115&selectedTaskRun=N884K73qSXyOqtWKSVbDig.0) build does not work on Windows 10 for some reason and neither does 115.7.0esr Asan bof build.
