Hm... so font_matching_entity sometimes returns [#<font-entity>] instead of 
#<font-entity>.
Something may be wrong with font cache or with font driver-specific match 
routine.
An output of (frame-font-cache) looks correct, so let's check both cases with 
the following
patch. My output looks like:

font_matching_entity: matched entity nil
font_matching_entity: matched entity #<font-entity x Misc Fixed ## 
JISX0201\.1976-0 medium r normal 14 75 110 70 nil>
font_matching_entity: matched entity nil
font_matching_entity: matched entity #<font-entity x Misc Fixed ## 
JISX0201\.1976-0 medium r normal 14 75 110 70 nil>
font_matching_entity: matched entity nil
font_matching_entity: matched entity #<font-entity x Sony Fixed ## 
JISX0201\.1976-0 medium r normal 16 100 110 80 nil>
font_matching_entity: matched entity nil
font_matching_entity: matched entity #<font-entity x Sony Fixed ## 
JISX0201\.1976-0 medium r normal 24 100 110 120 nil>
font_matching_entity: matched entity nil

and I do not see 1-item vectors here.
