Newer hostile mobs, such as the Evoker, Vindicator and Phantom despawn even after a nametag is applied to them.

Does naming the spawn egg stop them from despawning in the same way as a name tag or no? I think that may be the issue.
Can't reproduce. Evokers and vindicators don't even despawn at all – nametag or no.
