Also happens in Creative. When you click the bell with a block in hand, it places the block then disappears. You still have the item in your inventory though.
I have this "floor is lava" command (/execute as @a at @s if block ~ ~-.01 ~ minecraft:orange_wool run kill @s) set up in 17w50a that uses /kill and when I try to respawn it crashes.

so much for automatically being reopened...
Can confirm this is still an issue in 1.14.4. if I have animated structures with things like torches, tripwire, item frames, buttons, ect. they act as if being broken and dropping their respective items instead of just overwriting the block.
