Deceleration / Acceleration in liquid is affected by order of action

Summary:

Deceleration in liquid is affected by order of action.

Steps to reproduce:
  1. Hop in pool of water or lava

  2. Sneak( or block), and then start walking

  3. Start walking for a second and then sneak( or block)

  4. Notice that resulting speeds from step 3 and step 4 are different

  5. It shouldn't because after all the actions are done, player's state is same(other than motion)

Demonstration Video

Note:
It seems that blocking in lava have little or no visible effect described in this ticket.

Confirmed. Quite weird, and something tells me that this may be related to MC-48616.

EDIT: Indeed: if you walk, then sneak, and turn the other way (while still sneaking), your speed slows to almost none (akin to if you sneak first then walk).

Confirmed for 1.8.2-pre1.

Possibly relates to MC-64163?

Confirmed for 1.8.6.

This isn't really related to MC-64183. Only besides that the main topic being liquid.
I think this issue was, in fact, MC-48616, because they were fixed at the same time.
