   This issue might be a duplicate of existing issues. Please check:

   • opentui: can't read subagent session #3338: Issues with navigating to subagent sessions using shift+right keybinding - directly relates to the navigation aspect mentioned in this issue
   • Subagent results not always properly handled #3173: Subagent results not always properly handled - subagent output not being visible in parent session, requires navigating to child session to see content
   • Empty results from subagent on latest release 0.9.9 #2645: Empty results from subagent - subagent content disappearing/not appearing in main session
   • opentui: markdown is just rendered as text #3312: Content rendering issues in OpenTUI where markdown/formatted content isn't properly displayed

   Feel free to ignore if none of these address your specific case.

   Fast fix idea is to use +- same regexp which is used for stripping html xml content in ts code but instead of deleting it

   • mask: Detect tags <[A-Za-z!/](?:"[^"]*"|'[^']*'|[^'"<>])*?>, replace < > on something like {{LT}} {{GT}}
   • glamour: Then convert with glamour
   • unmask: Then convert {{LT}} {{GT}} back

   // pseudo code
   var tagRe = regexp.MustCompile(`(?is)<[A-Za-z!/](?:"[^"]*"|'[^']*'|[^'"<>])*?>`)
   
   func renderPreservingHTML(md string) (string, error) {
   	// 1) Pre: mask angles *only inside tags*
   	masked := tagRe.ReplaceAllStringFunc(md, func(s string) string {
   		return strings.NewReplacer("<", "{{LT}}", ">", "{{GT}}").Replace(s)
   	})
   
   	// 2) Glamour render
   	r := ToMarkdown(masked)
   
   	// 3) Post: unmask back to literal <...>
   	out = strings.ReplaceAll(out, "{{LT}}", "<")
   	out = strings.ReplaceAll(out, "{{GT}}", ">")
   	return out, nil
   }

   We are about to ship a full rewrite of the tui that will have a different markdown renderer, may be better to address this once that ships unless XML is a big blocker for u

   @istarkov yes! I bet this issue still exists there too tbh but if you were interested in making a fix, branching off that would probably be best.

   One note is the markdown renderer is about to be updated today or tmr probs so id hold off until that gets merged
