Block (tile) entities appear to lose their data client-side after failing to be broken by a player

Server Implementation

Paper

Server Version

1.16.5

Describe the bug

If a block entity is on the road or a plot that a player is not added to and they break it, it appears to lose its data from the perspective of the player until they either relog or reload the chunk that the block entity is in.

Examples:

• Signs appear to lose their text
• Spawners will appear as pig spawners
• Banners seem to become completely invisible
• Player heads appear as Steve heads

I'm pretty sure this is not a vanilla issue, as this issue is not present in protection plugins like WorldGuard.

EDIT: ONLY HAPPENS WHEN THE PLAYER IS IN SURVIVAL MODE!

To Reproduce

1. Set up a plot world
2. Have an opped player place block entities that have unique data (a sign with text, a spawner that isn't a pig, a player head that isn't Steve, etc.)
3. Have a non-opped player attempt to break them and observe as they appear to lose their data from the perspective of that player

Expected behaviour

Upon failing to be broken, block entities should appear as they otherwise would.

Checklist

• I have included a Plot debugpaste.
• I am using the newest build from https://www.spigotmc.org/resources/77506/ and the issue still persists.

Anything else?

Start by reproducing the survival-mode case described in the issue using signs, spawners, banners, and player heads in a protected plot. Compare the failed-break view with a relog or chunk reload, using the linked Plot debugpaste for context. Done means block-entity data remains visible after the failed break without either refresh.
