Analysis

This is an accessibility bug where links in the skillmap educator-info page lack discernible text for screen readers. The issue occurs on the auto-generated "Burstin' Balloons" educator info page at (redacted) The problematic element is a link with class ui linkpointing to/reference/controller/button/on-event` that has no visible text content, violating WCAG 2.4.4 (Link Purpose in Context). This prevents screen reader users from understanding the link's purpose.

Duplicate & Related Issues

Duplicates:

• #4871 (closed) - Nearly identical issue with skillmap educator-info pages lacking aria-labels on reference links in tables. This was fixed in March 2025.

Related Issues:

• #7137 (open) - Link accessibility issue related to color contrast, different root cause but same accessibility theme

Location Hints

Likely fix location: microsoft/pxt (pxt-core repository)

The educator-info pages are dynamically generated from skillmap markdown files by the skillmap rendering system in pxt-core. Based on the issue #4871 which had the same problem and was fixed, the rendering code that creates these reference link tables needs to ensure links have proper accessible text or aria-labels.

Relevant files in the pxt repository:

• skillmap/src/components/InfoPanel.tsx - Likely renders the educator info pages
• skillmap/src/App.tsx - Main skillmap application
• Related skillmap rendering components in skillmap/src/components/

The fix should ensure that when rendering reference links in educator-info pages, each (a class="ui link") element either:

1. Contains visible text content, OR
2. Has an aria-label attribute describing the link destination
