Steps to Reproduce:

1. Enter a pool of water that's at least 2 blocks deep
2. Start swimming
3. Without releasing the movement buttons, pause the game

Observed Results:
The player leaves swim mode as the game is paused, indicating that the movement is immediately cancelled upon pausing.

Expected Results:
The player remains in swim mode while the game is paused and only stops swimming if they are no longer moving when the game is unpaused (which is always the case, due to MCPE-188471).
