Almost freaked out when I saw this, thought it could be a new VSCode feature.

Turns out, it's a special ligature feature of the Maple Mono font https://font.subf.dev/

@[email protected] 😮 You can embed those into a font!?
@null yeah… there are coding fonts that does the usual fancy ligature stuff like convert -> to look like → (two chars, not one char) but this tag-like look is quite interesting 🤔
