Seems like this is still an issue. The front-end code is here in case someone wants to look into this: https://searchfox.org/mozilla-central/source/browser/modules/WindowsJumpLists.sys.mjs
And then there's this back-end code:
https://searchfox.org/mozilla-central/source/widget/windows/JumpListItem.cpp
https://searchfox.org/mozilla-central/source/widget/windows/JumpListBuilder.cpp

This bug isn't about the tab bar but about the Windows taskbar jumplist feature (see comment 1 for how that looked at the time).
