Steps to reproduce:
Enable vertical tabs
Open any sidebar menu other than the tabs menu
Press the menu item 'Show Vertical Tabs Sidebar' or press the appropriate keyboard shortcut.
The expected behaviour is that the vertical tabs sidebar is shown. Instead, however, it first shows horizontal tabs, then if you press it again it switches to vertical tabs again and shows the vertical tabs sidebar. Also, pressing it more, it seems to not just show/hide the sidebar but also switch between horizontal and vertical tabs (an issue which was marked done https://orionfeedback.org/d/4266-vertical-horizontal-tabs-switching-needs-to-be-separated-from-showhide-tabs-sidebar).
Also, if multiple windows are open, it seems to affect windows that are not in focus too, unlike other menu bar items that only affect the window in focus.
