The Molang query "query.is_riding" no longer works on the behavior side.

Partner Rank: 2

Partner Team Reporting: Spark Squared

Verification builds and Platforms: beta 1.16.0.63 (Windows 10)

Summary:

The Molang query "query.is_riding" no longer works in behavior side animations and animation controllers.

Impact:

Custom riding positions per vehicle are no longer possible, therefore breaking upcoming as well as already existing Marketplace content (e. g. City Life 2).

Repro Steps:

1. Download and install the attached behavior pack.
2. Join a world with the behavior pack enabled
3. Spawn a rideable entity, e. g. horse, and ride it.

Observed Results:

The animation controller logs into chat that is was loaded, but doesn't log that it has switched to the second state.

Expected Results:

The animation controller should print "Switched to Riding State" into chat as soon as the player rides an entity.

Screenshots/Videos attached: Yes

Yes, attached is a screenshot taken in the map City Life 2 of the player riding a skate board. In 1.14, the player would display a custom riding pose showing them upright no the skate board. (The player skin is not loading, but that is an unrelated issue)

Regression Builds:

query.is_riding was working fine in all 1.14 versions.

Notes:

query.is_riding works fine client side in resource packs.
