Flying player in creative or spectator mode swims up in water when pressing space (jump) and shift (sneak) at the same time

Can you please go a little bit more in detail, how can you interact with water then?

When you mean the particles, yes I can confirm that

if you are pushing space and shift with this mode in water, player interact like creative or survival mode. try it!!

I still don't get it.
Please attach screenshots.

okay... I'm interacting with water, and water push me up

It's not the same bug that https://bugs.mojang.com/browse/MC-46470 , Dinnerbone only fix the sound and particles of water but I can float in the water while I press the shift and space... it's uncomfortable to move in it...

And yes, is in the 14w31a

Confirmed for:

• Minecraft 1.8-pre 2 _When you press SHIFT and SPACE while beeing in water you fly until the surface and then you stop (like Pablo González Rubio said)

To clarify the report: When in creative or spectator mode, if you press both the fly and crouch keys while in water or lava, you will move upwards. This is because swimming is still enabled, and overrides the crouch key.

This issue relates to MC-46417.

Confirmed for 17w14a

Changed the report to include Creative mode as well since at least one of the tickets closed as duplicate of this report was only about Creative mode.
