Summary:
If you equip frost walker boots while not moving, this causes frosted ice to be generated once, even though it is only supposed to generate ice when moving. This didn't happen in 1.20.6. Possibly relates to MC-271459, due to it being another frost walker issue that didn't happen in 1.20.6.

Steps to reproduce:

1. Obtain frost walker boots.
2. Stand close to a body of water.
3. Make sure that you don't move.
4. Equip the frost walker boots.

Observed result:
Frosted ice was generated.

Expected result:
Frosted ice should not be generated.
