The top-right Preview | Markdown editor leaves `**` and `*` literal when CJK punctuation sits against the markers. The classic side preview uses markdown-it, so an extension can fix it through `markdown.markdownItPlugins` (`markdown-it-cjk-friendly`). Native Preview is a separate renderer and ignores that extension. There is no setting or extension point for it.

```md
**该星号不会被识别，而是直接显示。** 这是因为它没有被识别为强调符号。

此处 **强调（标记）** 紧接汉字。

```

Expected: both spans, including the punctuation, render as bold. Actual: the asterisks stay visible.

This is [CommonMark issue 650](https://github.com/commonmark/commonmark-spec/issues/650). The flanking rule, and a spec that stays identical to CommonMark for non-CJK input, is in [tats-u/markdown-cjk-friendly](https://github.com/tats-u/markdown-cjk-friendly). Please use that rule in the native Preview parser. An extension hook equivalent to `markdown.markdownItPlugins` would also let us fix it ourselves.

Same root cause also affects bold in agent chat replies. Repro and fix suggestion here: [Bold markdown breaks when CJK punctuation is followed directly by CJK text](https://forum.cursor.com/t/bold-markdown-breaks-when-cjk-punctuation-is-followed-directly-by-cjk-text/177950)
