Brief Description:
It seems that sometimes if I have fly activated, and I step through a portal (may be walking on ground or flying through), that may sometimes get stuck in blocks on the other side, or may arrive under the desired arrival location (may be underwater).

I have been trying to observe the vicinity when this occurs, and I think that most often when this happens, the arrival location may have 1/2 block slabs or carpet at the level of the bottom of the portal, and I guess I get trapped in the 1/2 slab or carpet or may even arrive under, in water, if the area is built above water.

Instructions:
1. Activate fly
2. Fly/walk through a portal like cookieland
3. If you get stuck, /warp towns , or /spawn to free yourself of your new land locked bounds.

How many times did you recreate this bug?:
I believe when this does happen, it happens only when I have fly enabled, and when the arrival location has 1/2 block slabs or carpet to step upon immediately outside of the gate.

Result:
I get trapped and cannot move, and my toon POV seems to be twitching. I can not jump up to get out (like how sometimes people arrive in a whole 1 block and can jump up to get out). I must warp out in order to free myself.

Expected Result:
I would travel through portals without having to deactivate fly, for fear of getting stuck or drowning.

Evidence:
A

 

I just walked through the NetherLand portal, and got stuck. The ground was a gravel block at portal bottom height.
