Unable to disable script manager from toolbar button

[srjjgm]

The popup menu that opens when clicking the script manager button in the toolbar (#userChromejs_options) has a problem in version 137.
All options work normally, except enable/disable userChromeJS. Clicking this option does nothing. It doesn't even appear "checked".
But this option works normally in the Firefox menu button popup (hamburger).

Since there have been a lot of changes in the code recently, I may have done something wrong here, so I would like to know if anyone else is having this little problem.
