I tried downselecting the rsvg library in the package manager to prefer
the C only implementation, rebuilt Emacs and see the same behavior.

  1 $ pkgin se rsvg
  2 pkgin se rsvg
  3 librsvg-2.58.0nb1 <  SVG library for GNOME
  4 librsvg-2.40.21nb18 = SVG library for GNOME (2.40.xx branch, C only)
  5 ruby31-rsvg2-4.2.2nb1  Ruby binding of librsvg
  6 ruby32-rsvg2-4.2.2nb1  Ruby binding of librsvg
  7 ruby33-rsvg2-4.2.2nb1  Ruby binding of librsvg
  8 
  9 =: package is installed and up-to-date
 10 <: package is installed but newer version is available
 11 >: installed package has a greater version than available package
