Tadpoles are not babies according to is_baby predicate flag

The bug

The is_baby entity predicate flag considers tadpoles to not be babies. They pass when is_baby is set to false and fail when it’s set to true.

How to reproduce

1. Spawn a tadpole

2. Run /execute as @e[type=frog] if predicate {condition:"minecraft:entity_properties",entity:"this",predicate:{flags:{is_baby:1b}}} run say baby

Expected result

Should say “baby”

Observed result

No output
