Sprint-swimming stuck at water surface

Short description of the issue:

When sprint-swimming upward while looking at a low angle underwater, the player gets stuck at the water surface and cannot rise further, even when looking up higher, unless they re-enter the water or toggle the sprint-swim key.

Steps to reproduce the issue:

1. Create a new world and find a body of water (river or ocean).

2. Jump into the water.

3. While underwater, tilt your view slightly upward (not too steep) and hold Ctrl to sprint-swim upward.

4. Once your body reaches the water surface, look up higher while still holding Ctrl.

Expected result:

When looking up higher while sprint-swimming at the water surface, the player should rise out of the water, jump into the air, and then fall back into the water.

Actual result:

The player gets stuck at the water surface and cannot rise further, even with a higher view angle. The only way to resolve this is to exit and re-enter the water, or release and re-press the Ctrl key.

Additional Notes:

• I have not measured the exact view angle required to trigger this.

• This issue appears to exist in most Minecraft versions, not just 26.1.2.
