Accessibility Checker should ignore equations

Accessibility Checker should ignore equations

Canvas white logo

This behavior has been resolved and deployed to the production environment.



When an equation contains a “.” the Accessibility Checker will flag the equation for using the image file name as alt text.

Expected Behavior


  • Instead the Accessibility Checker should ignore equations altogether

  • Equations containing “.” should not be flagged by the Accessibility Checker


Manually remove “.” from the equation’s alt text. Though this does cause a problem for screen readers since the alt text no longer matches the equation being displayed in the UI.

Steps to Reproduce

1. Create and publish a course.
2. Create any content that uses the RCE (in this example I am using a Page).
3. Create and insert an equation that contains a “.” anywhere in the equation.
4. Wait a few seconds and notice that Accessibility Checker flags the equations.
