Z-fighting and clipping when placing pots, candles, sea pickles, and banners on top of decorated pots.

When a pot (the small version that you can place plants into), four candles, two or more sea pickles, or a banner is placed on the top of a decorated pot (the new block associated with archaeology) these items will either visibly clip through the "walls" of the upper portion of the pot or occupy the same space as the upper portion, causing Z-Fighting. This occurs with other blocks such as chains and fences but is not as distracting as these blocks appear to simply be protruding from an opening at the top of the pot and do not clearly clip through in any illogical way. 

Steps to Reproduce:
1. Place down a large Decorated Pot block.

2. Place a small pot block, four candles, a banner, or two or more sea pickles on the top surface of the Decorated Pot block.
