Summary

In the specific world that I have uploaded, I cannot move through pressing "W", "A", "S" or "D" on my keyboard when I am flying.

Steps to Reproduce

1. Download, import and open the world "Superflat1.mcworld" that I have uploaded.

2. Press "Space" on keyboard twice to "be in" flying.

3. Press "W", "A", "S" or "D".

Observed Results

You get stuck and cannot move.

Expected Results

You can move by pressing "W", "A", "S" or "D".

Notes

1. For the world "Superflat1", it was created in the end of 2019, in other words, it was not created in the version 1.19.10. I created its copy in the version 1.18.0, when the program told me that it would help me to make the world deeper and higher. Using the copy "before1.18.0-superflat1.mcworld" to load, the bug can be reproduced.

2. The bug had been reproduced on the platform of Windows and Android by me.

3. I could still move up and down by pressing "Space" or "Shift" when flying.

4. Players who join in the world "Superflat1" by the time in newer versions can flying normally. For example, if a player use 1.19.10 or 1.19.40 to join in the world, they can flying normally.

5. If you "be in" flying when you are moving, you will slow down to standstill, instead of stopping immediately.

6. Around the worlds that on my devices, I can only use the world "Superflat1" to reproduce the bug. In any other world created in the older versions, the bug can't be reproduced. If you can reproduce the bug in other worlds, I think it's a good idea to upload your world(s).

7. In the videos, you can look at the virtual cat at bottom right to know which key I was pressing (except the "Shift", because I don't know how to add it to the virtual cat. But you can still look at the Paper Doll at top left to know whether I was pressing "Shift").

8. My English is not so great and I hope you can understand this report and my comments below.
