Summary

The Collaborative Editing is changing(removing) the HTML markup from pages. If you disable the Collaborative Editing, the markup remains.

Steps to Reproduce

1. Disable the Collaborative Editing.
2. Go to any existing page.
3. Paste the following CSS through the Source Editor:

   <h2 style="padding: 25px; color: rgb(81,85,94);background-color: rgb(243,243,245);">Testing Padding Styling</h2>
   

4. Save the changes.
5. Edit the page again.
6. The style will continue to use the "padding" html code.
7. Update the "padding: 25px" to "padding: 50px"(through the Source Editor again).
8. Save the changes.
   • Confluence will show the changes.
9. Enable the Collaborative Editing.
10. Edit the page.
11. Go to the Source Editor.
12. The "padding" parameter is missing.

Expected Results

The "padding" will continue to exist during the editing mode.

Actual Results

If the Collaborative Editing is ON, the changes("padding" in this example) will disappear upon page edit initiation.
