Player momentum stops when sliding to jump button w/ swap jump and sneak

(Mobile devices only)

When you move forward with the forward button and slide your finger to the jump button, you jump and keep sprinting/walking. Ideally this should work for other directions too, but it doesn't.

Steps To Reproduce: 

1. Open Minecraft->Settings->Touch->Swap Jump And Sneak and enable it.

2. Open a world/server/realm.

3. Press and hold the forward direction button.

4. Without releasing, slide your finger to the jump button. [If done correctly you will keep walking forwards]

5. Now repeat steps 3 and 4 for other direction buttons (Left, Right, Backwards). 

Observed Results: The player stops walking while doing steps 3 and 4 for other direction buttons.

Expected Results: The player keeps walking while doing steps 3 & 4 for other direction buttons.
