The latest firefox update introduced tab groups, something I've been eagerly waiting for ever since chrome released it! However, my firefox's tab groups don't hide the tabs correctly. In the video demo I see that when you click on the name of the tab group, it should collapse all the tabs and hide them. In my firefox, when I click the tab group name, the tabs don't get hidden as expected. Here is a video that shows the bug I'm referencing: https://imgur.com/a/8ewW1a2 I tried disabling all my extensions and restarting firefox, also tried in private mode, and it still was having the same experience. Are there any about:config settings that I might have accidentally changed that could be causing this? Thanks!
