Steps to Reproduce

1. Create with a page like this
   Source code by Confluence Source Editor

   <p>AAAA</p>
   <p>
     <ac:image ac:height="250">
       <ri:attachment ri:filename="IMG03.jpg"/>
     </ac:image>
   </p>
   <p>BBBB</p>
   <p>
     <ac:image ac:height="250">
       <ri:attachment ri:filename="IMG01.jpg"/>
     </ac:image>
   </p>
   <p>CCCC</p>
   <p>
     <ac:image ac:height="250">
       <ri:attachment ri:filename="IMG02.jpg"/>
     </ac:image>
   </p>
   
   

   

1. Edit the page and move Move IMG01.jpg and IMG02.jpg above text “BBBB” by drag and drop
   
2. Save the page
   The blank lines are added at the position that the moved images were located at. The lines were not appeared in the edit mode at the previous step.
   

Expected Results

The bank lines should not be added. Or at least, the blank lines should appear after drag and drop in edit mode so that user can delete it immediately.

Actual Results

The blank lines are added at the position that the moved images were located at. We can see the source cod like this,

<p>AAAA</p>
<p>
  <ac:image ac:height="250">
    <ri:attachment ri:filename="IMG03.jpg"/>
  </ac:image>
</p>
<p>
  <ac:image ac:height="250">
    <ri:attachment ri:filename="IMG01.jpg"/>
  </ac:image>
</p>
<p>
  <ac:image ac:height="250">
    <ri:attachment ri:filename="IMG02.jpg"/>
  </ac:image>
</p>
<p>BBBB</p>
<p> </p>
<p>CCCC</p>
<p> </p>

Workaround

Open the page after saving and remove blank lines ‘<p> </p>’ manually.
