Enable the click-to-open-menu, and the "community" button doesn't bring any more to ythe homepage.
Not if it should be considered a bug.
Note sure it can be. It will still get you to the home page if you use right click > open in new tab (which I do sometimes). Otherwise I just use the linktree directly underneath, which is nice and big and easy to target with brain in neutral. :)
ETA: It's partly because of things like this that I am not in favour of complicating the linktree with extra dropdowns and such. I think it should remain as a minimal collection of direct links.
Well, likely not a bug then.
