[MCM-855] query.is_in_ui no longer works in mob inventories

Partner Rank: 2

Verification builds: 1.13.31.0, 1.14.0.2, 1.16.100, 1.16.200
Regression builds: 1.13.1.0

Summary: Previously, query.is_in_ui was set to 1 when rendering a mob inside of its inventory preview (e.g. horse inventory). Now it's set to 0.

Impact: This prevents us from rendering the entity in that preview the way we want to, which affects a mechanic in an upcoming map.

Repro Steps:

Download and open the attached world
Right-click the llama to ride it
Open your inventory

Expected Results: Llama in preview is gigantic (see attached screenshot).

Observed Results: Llama in preview is regular size. Animation is not working because query.is_in_ui is wrongly returning 0.

Screenshots/Videos attached: Yes

Notes: I have not tested this query in other scenarios.
