The command /fill delete blocks, but not the tile entity.
(Exemple : delete a sign using /fill and replace another sign at the same place, it will appear with the previous text.)

This is not really a "duplicate". I mean the block has been correctly removed, but when i deleted it using /fil and replaced it after it reappeared with the same text. But the block HAS BEEN REMOVED.

Step to reproduce:
-Place a sign and write "MC-45159", for example.
-Delete it using the /fill command
-THE BLOCK IS DELETED
-Replace a new sign with your hand, at the same place

What i was expecting to happen : The sign should reapper empty.
What happened : The sign reapperd with written "MC-45159".
