When using a blighted flint and steel on furniture, furniture disappears.

So I have been decorating my realm and thought that it would be neat for that furniture to be lit up, I tried the blight flint and steel, but the furniture disappeared. It seems to happen since the flame updates and removes the furniture rather than itself. We have these sort of custom phantom/ghost blocks that dont have any collisions but still are a block, many props have both the barrier and that phantom block. Usually if you place something there it gets removed and returned to your inventory, but not this.
