Holding down right-click only places one boat

This bug was originally discovered whilst testing for MCPE-178055 and MCPE-177283

In recent previews, holding down the use/place button, will only result with a single boat being spawned. Multiple boats can still be spawned in by double-clicking or spam-clicking (as long as there isn't another entity in the way).

Steps to Reproduce:

1. Pick a boat (in creative)
2. Hold down the use/place button, whilst aiming at a block.
3. Start strafing, whilst keeping the place/use button held.

Observed Results:
Only one boat will be summoned.

Expected Results:
Multiple boats should be summoned, like in 1.20.51.
