Problem

Texts with class="confluence-embedded-file-wrapper confluence-embedded-manual-size" options are displayed incorrectly in Confluence 9

Environment

Confluence 9

Steps to Reproduce

1. Install Confluence Source Editor
2. Create a new page and save it.
3. Edit the page and click the <> button 
4. Add the following example storage format: 

      <span class="confluence-embedded-file-wrapper confluence-embedded-manual-size">
       <span style="color: rgb(51,51,51);text-decoration: none;">
         <span style="color: rgb(23,43,77);">Lorem ipsum dolor sit amet, consectetur adipiscing elit.</span>
       </span>
     </span>

1. Publish the page

Expected Results

The text should be displayed as it was shown in the editor.

Actual Results

Render as shown in edit mode.

Workaround

Editing the page and reapplying the text format using the UI seems to fix the issue. It converts the source to something like this:

<p>          Lorem ipsum dolor sit amet, consectetur adipiscing elit.     <span class="confluence-embedded-file-wrapper confluence-embedded-manual-size">   </span>
</p> 

Another possible workaround is to use the custom CSS below. 

.wiki-content .confluence-embedded-file-wrapper.confluence-embedded-manual-size {
max-width: none !important;
}
