Sneaking on the bottom of a climbable block will cause you to slide

If you're ducked, on the ground, and you're in the same block with a ladder or other climbable block, then you'll slide like on an ice block.

Reproduction provided by user-f2760

Simply place a ladder, move into it, and sneak (moving will then become as if on the ladder, even if you didn't climb it)

Expected Result

You wouldn't slide
