Stationary hitbox-based entities seem to stop working

The bug

If an entity based on interacting with hitboxes doesn't have any velocity anymore (for example with the NoGravity tag and flying long enough) they don't seem to interact with hitboxes anymore.

How to reproduce

1. Set up and activate a repeating command block with the following command:

   execute as @e run data merge entity @s {NoGravity:1b}

2. Throw a bottle o' enchanting

3. Follow it until it doesn't have any velocity anymore

4. Touch it. You will notice that it doesn't break as it should.
