"execute if items ..." can cause server to fail to load function during start

noted that two functions refused to load during server boot up, issuing a /reload fixes the issue similarly to MC-305698

The logs show

I didn’t catch this the last time, because I thought the line offset might have been off and dismissed it as the same issue

execute if data storage evo slot run function evo:update_spawn_egg
data remove storage evo slot

looking through all my other random projects it seems the unique thing about those files are those are the only places where I use the tilde functionality

attempting to verify my assumption proved me wrong;

creating a datapack with a function that is just

execute if items entity @s contents minecraft:acacia_boat[!minecraft:attack_range~{}] run say foo

does not fail to load during start up, nor does it with !minecraft:custom_data~{} or with !minecraft:custom_data~{fixed:true}

but it does fail if I use allay_spawn_egginstead of acacia_boat.

So to reproduce, make a datapack with one function;

execute if items entity @s contents minecraft:allay_spawn_egg[!minecraft:attack_range~{}] run say foo

function fails to load when server starts up, /reload makes the function available.
