Accessibility Checker should ignore equations

[#1]

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

Description

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
  or

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

Workaround

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.
