Adjust Held Item and Hover Information for Visibility

[Murklak]

When holding a stack of items with an item count and while hovering over another item, the two pieces of information overlap. This makes it difficult to know how much you're holding while dropping one item at a time onto another stack. Either moving the hover window in every case, or moving the two pieces of information apart in the specific case, would alleviate the conflict. Hopefully, you can find simple and elegant solution.
