I mention this because you asked about uses of standalone
minibuffer frames.  But I'm pretty sure it won't help you.
I didn't try from `emacs -Q', and my setup is far from
`emacs -Q'.

I use a standalone minibuffer frame.  I have eldoc turned
on and `minibuffer-auto-raise' = t.

I don't see (e.g. with Emacs 26) what you describe.  In my
case focus does not switch to the minibuffer frame.

I'm using MS Windows.  Perhaps the window mgr is involved
here, switching the focus to the minibuffer frame in your
case?
