调研方向
阅读 internal/htmlutil/markdown.go 和 htmlutil.go，重点查看 actionTextAttachment() 以及 walkNode 中的 action-text-attachment 分支；将它们与 figure() 和 findAttachments 中现有的 HTML 内容处理进行比较。使用提供的嵌套 text/html 示例复现问题。当渲染后的 Markdown 和纯文本都显示嵌入的邮件正文，而不是附件占位符时，即为完成。

描述
What happens
Some inbound HTML emails render as nothing but a placeholder, in both hey thread read and the TUI:
"body": "📄 attachment"
The TUI shows the same file icon and "attachment", but there is no real attachment: the TUI footer has no attachment bindings, and hey attachment list correctly reports 0. The actual body text is never shown.
The text in the email's body can be retrieved by running hey thread read --html and pulling the text out of the raw html.
The email I noticed this on has some personally identifying information so I'm not providing it all in this issue, but I am happy to forward the email or provide the raw html to a developer if it would help.
Version: hey 1.10.0
Possible Cause
I'm sorry, I'm not a software developer myself, but after I had Claude Code extract the text in the email for me, it gave me this explanation:
HEY wraps the body twice. hey thread read --html gives this structure (trimmed):
<figure data-trix-attachment='{"contentType":"text/html","content":"<shadow-content><action-text-attachment content-type=\"text/html\" content=\"<p>Hi all, ...</p>\"></action-text-attachment></shadow-content>"}'>
</figure>
In internal/htmlutil/markdown.go:
figure()correctly unpacks the outer Trix attachment viam.embedded(attachment.Content).- The inner
<action-text-attachment content-type="text/html" content="...">then goes toactionTextAttachment(), which treats it as a file. It has no filename and the content type istext/, soattachment()writes📄+ the fallback nameattachment.
findAttachments in htmlutil.go already handles this shape (the isHTMLContentType(...) && getAttr(n, "content") != "" case recurses into the content), so the renderer and the attachment finder disagree about the same node.
Suggested fix
In actionTextAttachment(), render an HTML-typed node that carries content as embedded markup, the way figure() does:
func (m *markdownizer) actionTextAttachment(n *html.Node) {
if isHTMLContentType(getAttr(n, "content-type")) && getAttr(n, "content") != "" {
m.embedded(getAttr(n, "content"))
return
}
// ...existing handling
}
walkNode in htmlutil.go (the plain-text path) has the same gap in its action-text-attachment case and probably needs the same change.
Workaround
hey thread read <topic_id> --html and strip the tags yourself; the text is all there.
