Attachment: dragexit should always reset dragoveritem in Australis' customize mode,

D'oh.

Comment 5

[:Gijs (he/him)]

(normally this case is caught by dragexit, but if you move the mouse really quickly it might not be, and so stuff ends up being perpetually transformed - this patch fixes it by ensuring dragend always resets the dragoveritem if necessary)

Also, although this is serious, as soon as you exit customize mode, stuff is fine again, so I don't think it's P1 after all. :-)
