When a list item's first block had children, like a parsed <details> toggle, the list item content split inside that block. The leftover block had children but no content, so parsing threw. Split after the whole first block and keep its children nested under the list item. Fixes TypeCellOS#3189

- Around line 97-103: Update the Markdown parsing/export boundary used by
blocksToMarkdownLossy and tryParseMarkdownToBlocks so escaped <details> tags
remain literal text instead of being consumed as HTML; ensure getListItemContent
preserves that text in the list item, and update the round-trip test to assert
the parsed item contains <details>.

Markdown export wrote text like <details> as is, so loading the file back read it as HTML and dropped the text. Escape < where it would start a tag, comment or autolink, and accept \< in the parser. Refs TypeCellOS#3189

Text like \<details> exported as \\<details>, which the parser reads as a literal backslash followed by raw HTML, so the text was lost. Double the backslashes right before an escaped < so they load back unchanged. Refs TypeCellOS#3189

Summary
Fixes #3189.
tryParseMarkdownToBlocksno longer throws when a numbered or check list item starts with a<details>tag. Markdown export now escapes HTML-like text, so a list item whose text is<details>loads back with that text.Rationale
getListItemContentflattens the first parsed block into the list item and keeps the rest as children. It cut only the first block's content node out of the parsedblockGroup. When that block had children, like a parsed<details>toggle, the cut landed inside itsblockContainer. The leftover container had ablockGroupbut no block content, so parsing threwblockContainer must start with a block content node.The crash also hid a round-trip loss. Markdown export wrote text like
<details>unescaped, so the parser read it back as HTML and dropped the text.Changes
blockContainer, not only its content node.<details>body stays nested under the list item.<in text where it would start an HTML tag, comment or autolink, so<details>exports as\<details>. Backslashes right before an escaped<are doubled, so text like\<details>also loads back unchanged. A<before a space or digit, as in1 < 2, stays unescaped. Code spans and code blocks are unchanged.\<as a backslash escape in the Markdown parser, as CommonMark does.Impact
List items whose first block has no children parse the same as before, since the two cut positions match in that case. A list item starting with
<details>now becomes a list item with the summary as its text and the details body as its children. Exported Markdown changes only for text with<before a letter,/,!or?. No existing export snapshot changed.Testing
1. <details>,- [ ] <details>, and a numbered item holding a full<details>with a summary and body.<details>, for a paragraph with tag-like text, an HTML comment and1 < 2, and for a paragraph with backslashes before tag-like text. All three snapshots keep the original text.mainand pass with this change.@blocknote/coreunit tests (1,095) pass.pnpm lintreports the same output as onmain.Screenshots/Video
Not applicable; the change is in parsing.
