Accessibility Toolkit fails to fix nested html elements

Steps to reproduce:

1. Create a page activity, and in the content section, type nested <b> and <i> elements like so:

• <b><i>This is some text</i></b>

1. Run analysis on the course – note the two text errors we just created.
2. Open the Wizard and fix the inside error first. In this example, we would fix the italics error first.
3. Then, fix the outer error. In this example, we would fix the bold error.
4. Note the confirmation message indicating the error is fixed, but the bold error is still listed. Navigating to the content reveals that the <b> tag is still present.

 
The issue arises when the inside tag is fixed first. Then, when attempting to fix the bold error, it can't seem to find the original text. There does not appear to be a way to reanalyze.
