[bug] can't place tiny component on snow layer

[lublak]

if you place it on a snow layer, it is not really added. But the snow is removed. The block simply goes back into the inventory.

I'm assuming you're trying to place a component without a panel. What is probably happening is that it creates the block entity for the component which causes the snow to be removed. Then the block entity gets the click location vector and tries to place the component there. Since the user clicked on top of the snow, it's not able to calculate where the component should be placed. I suspect the same thing would happen if you clicked against a tall grass.
