Show Sidebar in full screen mode (at least on macOS)

Here is a problem with the Sidebar feature(“Always” chosen in Show Sidebar settings):

Yeah, this is not a feature request but a bug as far as I can tell.

idk if the total silence and few votes express that it shouldn’t have been posted as a feature request, or because the sidebar feature is relatively new or because all mac users use Safari and not brave, but the fact remains that the sidebar feature is not working in full screen mode.
