In bedrock previews, after using the chat bar and leaving, next time switching slots in my hotbar it points vision along the nearest coordinate axis

I discovered this just yesterday when I was using commands to enchant my gear in creative mode, and when I would exit the chat bar and move the hotbar indicator to the next item, it would make my vision look straight ahead, straight down, or straight up, whichever direction was closest to my field of view, even though I was looking diagonally. I was confused at first, and it sort of reminded me of how when exiting a world and rejoining it makes one’s vision point straight ahead.
