It is now impossible to delete an entity's name.

Previously, setting an entity's CustomName to "" would clear its name entirely.
This is the only method to do this, as /data remove doesn't work on CustomName, at all.
(see MC-128225 for that issue)

However, with the recent changes to text parsing, setting an entity's CustomName to "" wouldn't work anymore (it still ran, but as if nothing happened), removing this tool from the system for good. It is now impossible to delete an entity's name.

Please fix this, as this has been a thing for so long before 1.20.3 (and now 1.20.4)'s release.
Such a change permanently removes datapack creators' abilities to erase an entity's name, which is crucial for projects that does that very thing, which has been around for a very long time.
