bug#59347: 29.0.50; `:family` face setting ignored

But my `font` pattern doesn't specify a "weight".

Ignoring a "bold" setting would probably surprise/disappoint users just
as often.

Could be, indeed.  I don't actually care about the width of the font
when I request `DejaVu Sans`.  This said, if I use

    (:family "DejaVu Sans" :width normal)

I still don't get `DejaVu Sans` but I get a "normal" (hence wider)
misc-fixed instead :-(
