The buffer name uses the bold variant of the font.  If the font you
specified doesn't have a bold variant, Emacs will not be able to
display it.

Again, because that part of the display needs the italics variant of
the font.

Why do you insist on forcing on Emacs a specific fully qualified font
definition?
