[NTG-context] Emojis showing up in black instead of colours

[Vincent Hennebert via ntg-context]

Hi there,

freshly upgraded LMTX installation. TwemojiMozilla.ttf downloaded from
GitHub [1].

The following:
    \usemodule[fonts-emoji]
    
    \definefontfeature
      [overlay]
      [default]
      [ccmp=yes,
       colr=yes,
       dist=yes]
    
    \starttext
    
    {\definedfont[name:twemojimozilla*overlay] \ShowEmoji}
    
    \stoptext

gives me pages of emojis, all black. According to what is described on
Stackexchange, I should be getting colours. Am I doing something wrong?

Thanks,
Vincent
