Comically long key pressed block & other input bugs

I was trying to undo and redo dragging a key pressed block into a list block, but then Snap! created this monstrosity:

It didn't persist with saving, sadly.

BONUS BUG! While trying to replicate this glitch (which I failed to do), I managed to somehow make a block which permanently has a shadow and makes inputs very long, remove the list input from a block and create a cyan halo that's waaay larger than the block it's being dragged into.
(excuse the lazily removed background, I just didn't want to really hurt the eyes of dark mode users)

yeah... this is a bug with undrop and redrop. I try to not use them to avoid this problem (also because they can make you lose stuff like large text strings in inputs, and can really mess up code.)
