Whenever block entities are predicted to be broken on the client but later are confirmed to not be broken by the server the server doesn't send block entity information / the client doesn't remember the block entity information.
Steps to Reproduce:
Start a server with spawn protection
Op yourself
Op another player (to enable spawn protection)
Place a sign and write some text on it
Deop yourself
Break the sign
You will see that the client thought the sign could be broken and thus removed block entity data. Either re-logging or reloading the chunks will cause the sign to display properly.
