According to what I see here 120755 (#x1d7b3) is the same kappa symbol
as #x1d779, just in italic form. Not sure why Emacs on your system
displays the former when you request the latter, but at least it's the
same letter. Perhaps the font driver substitutes one for the other?

Math fonts are notorious for requesting huge ascent and descent
values. I always disable them using fontsets.
