All emojis turn into a ㊙️-stack when exporting to SVG #6611
Description
Description
When using some versions of Noto Color Emoji and compiling to SVG, all emojis will turn into U+3299 ㊙️. Or more precisely, all emojis in the font are stacked together, and ㊙️ is the topmost one.

This is an SVG-only issue. Exporting to PDF is fine. (Of course, html.frame is also affected.)
Background: Myriad-Dreamin/tinymist#1907.
I guess it's related to #4335 and typst/typst-dev-assets#2?
LLM tells that there are three kinds of emoji fonts: 1. COLR / CPAL, 2. CBDT / EBLC or PNG, 3. SVG. Maybe some formats are not supported? Is the support status documented somewhere?
Update: https://www.colorfonts.wtf/ says that there's a 4th kind: SBIX.
