When dumping this part of the font-lock-comment-face face specification matches:
 (t (:weight bold :slant italic)) so the face is created with bold and
 italic properties.

later at run time face-spec-choose is called this will match: 
"((class color) (min-colors 8) (background light))"
but because it specifies no properties face-spec-set returns 
nil => face-spec-reset-face is not called in face-spec-set => the bold
and italic attributes are kept... 

Is this a corner case that was not exercised until now? Or is this by
design? 

In case this is by design, then a better "fix" would be this:
