The item spawned by a /give command can be detected by commands for a single server tick after the command is run

Steps to reproduce:

1. Create and empty world with no item entities
2. Place and power a repeating command block with the command "execute as @e[type=item] run say hello"
3. /give yourself any item

Observed result:
hello is printed once.

Expected result:
hello is not printed at all.
