What's happening is that the Markdown parser isn't yet parsing
<bas an HTML tag, whereas it is<div(or<por any block tag). As such, HTML-specific behavior like the auto-closing isn't firing when a>is typed. This parsing behavior matches the CommonMark spec (compare this and this example), but I agree that the outcome isn't great in this situation.It seems kind of hard to work around, though. The closing logic is implemented with an input handler, which runs before the
>is in the document (and thus in the parse).marijnh commentedon Apr 15, 2026
