Depends on D20308. The element which previews what will happen when you drop a task somewhere can cover the bottom part of the rightmost column on a workboard.
To fix this, I'm trying to just fade it out if you put your cursor over it. I tried to do this in a simple way previously (":hover" + "opacity: 0.25") but it doesn't actually work because "pointer-events: none" stops ":hover" from working.
Instead, do this in Javascript. This is a little more complicated but: it works; and we can do the fade when you get //near// the element instead of actually over it, which feels a little better.
