In-editor inline comments don't show within third-party macros

Issue Summary

With the new inline comments feature, working on Confluence got easier with the possibility to add these comments from within the editor.
Though that's a great feature, it seems it is not working well when an inline comment is being added within a third-party macro.

Steps to Reproduce

1. Install one of the below third-party add-ons on Confluence (for example):
   • Numbered Headings;
   • Table Filter and Charts for Confluence;
   • Content Formatting Macros for Confluence
2. Create a new page;
3. Insert a macro from one of the installed add-ons;
4. After typing some text within the macros, add an inline comment somewhere in this text;
5. Publish the page.

Expected Results

The inline comment is being shown in the text.

Actual Results

No inline comment can be seen.

Notes:

• It might be happening with other different third-party macros - the 2 mentioned above are just as an example, since they were macros we tested this behavior;
• From the published page, if we add ?focusedCommentId=COMMENT_ID#comment-COMMENT_ID at the end of the URL, the comment gets shown at the right side of the screen.

Workaround

Currently there is no known workaround for this behavior, but removing the content from within the macros will get the inline comment shown in the text.
