There is an instance (and related test) where the capitalization of "WordPress" is incorrect:

• Line 156 in editoria11y-wp.js
• Line 11 in editoria11y-dashboard.js

I would actually suggest changing the text to be clearer. Everything tested is "WordPress" one way or another, so a message like "Button missing link" or "Unlinked button" feels like a more descriptive phrase.
