Plasma-emojier fails to change emoji font with system

I recently decided to change my emoji font from noto to twemoji and applied the change by creating the following ~/.config/fontconfig/fonts.conf:

<?xml version='1.0'?>
<!DOCTYPE fontconfig SYSTEM 'fonts.dtd'>
<fontconfig>
 <alias>
  <family>sans-serif</family>
  <prefer>
   <family>Noto Sans</family>
   <family>Twemoji</family>
   <family>DejaVu Sans</family>
  </prefer>
 </alias>
 <alias>
  <family>serif</family>
  <prefer>
   <family>Noto Serif</family>
   <family>Twemoji</family>
   <family>DejaVu Serif</family>
  </prefer>
 </alias>
 <alias>
  <family>monospace</family>
  <prefer>
   <family>Noto Mono</family>
   <family>Twemoji</family>
  </prefer>
 </alias>
 <dir>~/.fonts</dir>
</fontconfig>

It seems to have correctly changed the emoji font in every application with the exception of the emoji selector which is still using the noto emojis. Is this a limitation with the kde emoji selector or is additional configuration needed?

I believe the Emoji Selector app is hardcoded to show Noto Emojis, as a workaround for misconfigured systems. Perhaps it should not.
