I found it also happens when placing a shelf over a block that is in the ground and there is another shelf where the item is supposed to be pushed out. There is a video of it in MC-300708. Can confirm it happens in 26.2
Yes. I think that the problem is that I have the sneak option at toggle mode and it makes the character go down even if I don't press the toggle button, I have been testing and it also happens in creative mode
