Summary:
3rd person view gets stuck in blocks in spectator mode.
In the java version, when the player in Spectator Mode turned on the third person view and is in blocks, the camera switches as if in the first person view, but when the player exits the blocks, it switches back to the third person view. In bedrock, the camera just gets stuck in blocks, which gives a very large twitching of the screen.
Steps to reproduce:
Switch to spectator mode (/gamemode 6).
Switch to third person view.
Give yourself the effect of invisibility.
Move in blocks.
Observed results:
The camera shakes a lot as it gets stuck in the blocks.
Expected results:
The camera in the blocks will be in the first person (and won't shake).
Can confirm.
