Improve Shulker and Bundle Preview Tooltip

The preview tooltip that appears when you hover over a shulker or bundle is a dull list of items that caps at a certain amount, after which it says "and n more." This makes it really unclear as to what items are stored in these inventories, and the plain list of items is annoying to read through in order to get an idea of what is stored in the inventory.

As a solution, an image of the full inventory of the shulker/bundle should be shown when you hover over it and hold shift. This is really clear and will show all items in the inventory.
