Issue Summary

If you have an image that has a text caption you can not highlight the text and add an inline comment. The comment feature is grayed out and when you hover on it you get the below message:

comments can only be added to text that doesn't contain an emoji, an macro or an @mention.

However, it's interesting that you can add the inline comment through the editor. 

Steps to Reproduce

1. Create a Confluence Page
2. Add an image
3. Add caption text to the image
4. Publish the page
5. Try to add an inline comment to the image caption.

Expected Results

You should be able to add the inline comment

Actual Results

You are unable to add the inline commend and are presented with the message:

comments can only be added to text that doesn't contain an emoji, an macro or an @mention.

Workaround

Edit the page and add the inline comment that you desire. This will create the inline comment and allow other users to leave comments.
