Auto jump works when floating on ice even when auto jump is off

Even with auto-jump disabled, sliding on ice when getting out of the water or briefly jumping between blocks of ice will cause the player character to automatically jump to the next block of ice. This bug was tested on the latest Minecraft snapshot.

The original video file showing the bug takes up a lot of space, and here you cannot upload files larger than 10 MB. Attached a compressed video and a screenshot. Full video in original quality at this link.
