Issue Summary

It's no longer possible to add inline comments to rendered text generated by the user macro attached to this ticket and/or any simple user macro with a body and mark it as Rendered. In 8.5.19, this was still possible. Now, when attempting to add inline comments to this text, you will see an error pop up with "We can't add your inline comment; the section you highlighted may contain a macro or user mention. Try highlighting plain text."

Steps to Reproduce

1. First, create a user macro.

   ## Parameters:
   ## @param title:title=Title|type=string|required=true|default=Test Macro|desc=The title of the macro
   ## @param color:title=Text Color|type=string|required=false|default=#333333|desc=The color of the text
   ## @param backgroundColor:title=Background Color|type=string|required=false|default=#f5f5f5|desc=The background color of the macro
   
   <div style="border: 1px solid #ddd; border-radius: 5px; padding: 10px; margin: 10px 0; background-color: $paramBackgroundColor;">
       <h3 style="color: $paramColor; margin-top: 0;">$paramTitle</h3>
       <div style="color: $paramColor;">
           $body
       </div>
   </div>

   Again, make sure to mark as Rendered.

3. Add the user macro to a page, and add some text to the body.
4. Save the page, and attempt to add an inline comment to the rendered text.
5. Using the same user macro, if you test this on 8.5.19, the inline comment works, and on 8.5.21, you will receive the error.

Expected Results

Inline comments are added.

Actual Results
