[MC-111809] Paintings unrender when entity data is updated rapidly

A painting will unrender itself after a few seconds of having its entity data updated.

Place a repeating command block with always active enabled with a command of:

/execute as @e[type=painting,distance=..20] run data merge entity @s {Test:1}

Place a painting within 20 blocks of the command block and wait a couple seconds
→ The painting and its hitbox will vanish. When destroying the block it's placed on, the painting will drop.
