---

**Issue 1: Confirmation popup too tall to scroll (50+ docs)**

**Root cause:** `SubmitConfirmationDialog` has no max-height or internal scroll on the document list. With 50 files, the list alone can push the "Confirm & Submit" button below the viewport.

**Fix:** Add internal scroll to the document list + cap at `max-h-48` with a "and X more files" summary. Buttons stay sticky.

**Files:** `client/components/dashboard/modals/SubmitConfirmationDialog.tsx`"#;

        let output = markdown_to_mrkdwn(input);

        // Bold should be converted
        assert!(
            !output.contains("**"),
            "Output still contains double asterisks: {}",
            output
        );
        // Single asterisk bold should be present
        assert!(output.contains("*Issue 1:"));
        assert!(output.contains("*Root cause:*"));
        // Code should be preserved
        assert!(output.contains("`SubmitConfirmationDialog`"));
        assert!(output.contains("`max-h-48`"));
    }
