Attachments on a page are broken after moving page trees between spaces

Summary

Attachments of child pages are missing if parent page was moved cross-space. Affects 5.8.16 and 5.8.17. Upgrade to 5.8.18 if you are experiencing this issue and resolve the currently affected attachments using these instructions.

Please do not confuse with https://jira.atlassian.com/browse/CONF-36497 when attachments are missing in case if move failed.

• Create empty page (this is the parent page)
• Create empty child page of the parent page
• Attach a file to child page. Click on file and see download prompt.
• Move the parent page to another space
• Navigate to child page, and attempt to download the attachment
