At mentions are replaced with a link to the page when cut/copy/paste page contents

Steps

1. I created an empty meeting notes page (using meeting notes blueprint)
2. Copy paste content from the previous meeting notes page (from a different confluence site)
3. Make changes then publish the page

Expected results
All the at mentions are for the right people

Actual results
Any at mention that was copied across from the previous page has been converted into a link to the current page.

Note
In Firefox, Adding and Copy/Paste the user mentions from the same page to the different location in the page will also convert the user mentions link to the current page link.

Workaround:

• Use a different browser (Chrome, Safari or IE).
• Use Source editor to copy user mention link block, and then place it in the desired page on the right spot with Source editor.
  eg. <ac:link><ri:user ri:userkey="2c95b09a672ba3b901672bac0dd80XXX" /></ac:link>
