The part where you requested a misc-fixed font.

Of course, it can.

And if it isn't because of size, it can be because of some other font
attribute, like weight.

Bottom line: you cannot expect Emacs to select a font from a family
you request, not with a 100% reliability anyway.  Emacs can decide not
to.
