I'm using a command block set in repeat mode to constantly check that a player head (styled as a cake) is at a given position. If the position is air, i.e. whenever a player breaks the head, it will be immediately replaced using /setblock.

Here is the command text being run:

execute if block ~ ~1 ~ air run setblock ~ ~1 ~ minecraft:player_head[rotation=1]{SkullOwner:{Id:[I;-1263558717,974606245,-1774197082,1862776698],Properties:{textures:[{Value:"eyJ0ZXh0dXJlcyI6eyJTS0lOIjp7InVybCI6Imh0dHA6Ly90ZXh0dXJlcy5taW5lY3JhZnQubmV0L3RleHR1cmUvY2M5YTg3MjI2ZmRhMDVhMWU2MjRlYmI3MmNmNzQwNjIzZTgxOTE4OWRmZWY1ODliNjgwNzdlNzVjMjQ4Y2U3OSJ9fX0="}]}}}

/execute if block ~ ~1 ~ air run setblock ~ ~1 ~ minecraft:player_head[rotation=1]{profile:NeunEinser}

Expected behaviour:
The head is replaced with the correct custom texture.

Actual behaviour:
The player head is replaced with the default Steve texture until either you move far away from the head and return, or log out and log in again. Using F3+A to reload chunks does not fix the texture.

Notes:

• Running the command in an impulse command block with a button, the head texture will be set correctly whenever it is placed.

• The same command worked correctly in 1.18.2 so this seems to be a bug that was introduced at some point since then.
