[NTG-context] Emoji color fonts not working on LMTX/Context MKIV

[Jairo A. del Rio]

I've tried the following from the manuals and adapted some code to see if
it works:

1.
\definefontfeature[svg][svg=yes]
\definefontsynonym[Emoji][file:emojionecolor-svginot.ttf*default,svg]
\definesymbol[bug][\getglyphdirect{Emoji}{\char"1F41B}]
\starttext
\symbol[bug]
\stoptext

The emoji has no color when compiled with LuaTeX. Furthermore, the log
includes a lot of lines like the ones below:


fonts > svg conversion > executing runner 'otfsvg': inkscape
--export-area-drawing --shell > temp-otf-svg-shape.log


fonts > svg conversion > processing 1829 svg containers

xml > core > load error: invalid xml file - parsed text

With LMTX it gives an error about mlib-svg.

2.

\definefontfeature[overlay][default][ccmp=yes,colr=yes,dist=yes]
\definefontfeature[svg]
[default][svg=yes]
\definefontfeature[bitmap] [default][sbix=yes]
\definefontfeature [colored] [default]
[ccmp=yes,dist=yes,
colr=yes,svg=yes,sbix=yes]
\definefontsynonym[Emoji][file:notocoloremoji*default,colored]
\definesymbol[bug][\getglyphdirect{Emoji}{\char"1F41B}]
\starttext
\symbol[bug]
\stoptext

What I get is:

fonts > png conversion > processing 3374 png containers


sh: 1: gm: not found


sh: 1: gm: not found


sh: 1: gm: not found sh: 1: gm: not found

...

and the same line repeating itself
...

close source > level 1, order 3, name
'/home/lol/lmtx/tex/texmf-context/tex/context/base/mkiv/cont-yes.mkiv'

! error: (file /usr/share/fonts/truetype/noto/NotoColorEmoji.ttf) (ttf):
loca table not found


LMTX prints a file without any emoji.


Only Twemoji Mozilla and Segoe UI Emoji worked for me, so, what am I doing
wrong?


I'm working with Ubuntu 20.04 LTS x86_64 and Inkscape 0.92.5 (2060ec1f9f,
2020-04-08) in case it helps. Thank you in advance.
