Thanks for the fix @FrankGameDev! Since this was fixed on 8.1, we can try to port this back to 9.x and 10.x as well.

Hi! Thanks @FrankGameDev, sounds good.
Also just a note for future PRs, usually it's not necessary to create backports beforehand - I apologize for the confusing wording of this comment! The "port to" labels added here mean that a Github action to auto-port will be attempted when a PR is merged, which is usually the easiest method to try before manually backporting (and will save you from having to transfer any review changes to the other PRs).
