This issue was reported and fixed in 132, but the fix was never backported to ESR 128. I'd post a comment there instead of making a new bug, but "You need permission to comment on this closed bug."

This commit can be directly applied to ESR 128 and it works.

The Bugbug bot thinks this bug should belong to the 'Core::Privacy: Anti-Tracking' component, and is moving the bug to that component. Please correct in case you think the bot is wrong.

Yep, while we cherry-picked the fix on Tor Browser, esr128 was never been set as affected in the original Bug.
FWIW, there will be just another 128 release (128.14, expected on August 19), and this fix would make that minor version fingerprintable, but it's not my call when it comes to Firefox.
