Selector parameter "name" no longer works for default entity names

The bug

I can’t test older versions, but I am pretty sure this used to work.

The name= option in a command selector finds entities with a specific name. This finds player names, dropped item names, and name tags. It’s supposed to also work for the default names of unnamed mobs, but apparently it no longer does.

How to reproduce

1. Drop an apple

2. /say @e[name=Apple]
   ✔ It finds the apple and prints “Apple”

3. Spawn a cow

4. /say @e[name=Cow]
   ❌ It doesn’t find the cow

5. /say @e[name=""]
   ❌ It finds the cow, and shows its name is indeed “Cow”

Expected behavior

Since the cow is named Cow, name=Cow should find it

Observed behavior

It doesn’t, but it works for items
