Steps to reproduce:

1. Create a new page.
2. Import a word document.
3. Mark some plaintext and create an inline comment.
4. Save the page.
5. Insert the "Numbered Headers"-macro and paste the commented text inside.
6. Save the page.

Expected Results:
Comments are visible.

Actual Results:
Comments are deleted.

Workaround "Page History" unfortunately doesn´t work: If I restore the page to an earlier version (where inline comments were visible), everything returns, except the inline comments.

Expected Results:
The whole page content is restored to an older version.

Workaround that worked: Edit -> Resolved Comments -> Mark resolved Inline Comment -> Reopen
