bug#47388: 27.1; eldoc-documentation-function is ignore in updated eldoc

[Alex Branham]

Because then we modify el-doc-functions because of the newer version of eldoc loaded. 

But the ignore value of el-doc-function prevents eldoc from working

Hopefully that helps, sorry for the brevity am on phone

But earlier you said, accurately, in fact it was your first sentence, that:

So if it was #'ignore and still is #'ignore what exactly is the
difference that (require 'eldoc) or (require 'eglot) is introducing??
