🐞"Undo the new sidebar!" does not undo the new sidebar when logged in to youtube.

Bug Report:

• Freshly installed the extension and the option to "Undo the new sidebar!" does nothing. New sidebar design remains unchanged whilst logged in. When logged out the option works as expected.

• Since when?: Now, fresh install of Windows, Firefox and this extension
• Browser: Firefox 145.0
• Are any errors shown in the Browser-Console?: NO
• Does the bug not happen when you log out of YouTube? Then please copy your experiment flags list twice (with & without the error to compare). Enter: yt.config_.EXPERIMENT_FLAGS into the Browser console on youtube (F12-Key - Or find it in the html source(ctrl+U)
  I don't understand this. When I try enter that into the browser console it just hides everything. Bug does NOT occur when logged out but DOES when logged in.

Reproduce the issue in Firefox with YouTube logged in and logged out, then compare the sidebar behavior and the yt.config_.EXPERIMENT_FLAGS value from the browser console. Trace the extension's sidebar handling from the relevant YouTube integration entry point; done means "Undo the new sidebar!" removes the new sidebar while logged in as well as when logged out.
