Partner Rank: 4

Verification builds: 1.16.100 1.16.200

Summary:
Using both unit_cube and geometry components on blocks results in geometry being ignored

Impact:
reduced versility of unit_cube tesselation optimisations

Repro Steps:

1. pen repro world unit_cube
2. look at block
3. close world
4. comment out ""minecraft:unit_cube": {}," in the block behavior of disco_block.json
5. open world
6. look at block

Observed Results:
If unit_cube component is on the block, geometry is not shown

Expected Results:
geometry and unit_cube should both work at the same time resulting in a unit_cube tesselated block that also has geometry (see slime/honey_block)

Screenshots/Videos attached: No, check the world, it would be a screenshot of a single block.

Regression Builds:
new feature

Note: Jason Major told me to report this as per AC/DLC discussion. Is likely a bug.
