A Web Compatibility intervention for this is now shipping in Firefox Nightly 114 as per bug 1805410. We will be uplifting this intervention into the 113 Beta as well, so that it'll be included in that release train.

The issue has an intervention in place and does not reproduce with the intervention pref set to true.
