Issue Summary

When we attach a pdf file in a page and change filename from the attachment section, in the storage format, below 2 tags gets added:

<ri:page ri:content-title="title of the page" ri:space-key="XYZ"

Later when you update the page, these entries will be removed and updates the page versions:

I only updated the page with simple "hi" but when i compared the page version, it also shows that page and space details were removed.
This gives wrong impression about the page versions.

Steps to Reproduce

1. Copy paste a pdf file on your Confluence Page.
2. Change the filename from attachment section.
3. check the Storage format and you will notice the "page" / "space" tags added.This will also be recored in the page version.
4. update the page randomly and both the tags added in step 3 will be removed from the storage format automatically.
5. The tag removal entries will also be updated in the page versions.

Expected Results

The tags should not automatically gets added/removed.

Actual Results

The below exception is thrown in the xxxxxxx.log file:
In the storage format, below 2 tags gets added:

<ri:page ri:content-title="title of the page" ri:space-key="XYZ"

Workaround

Currently there is no known workaround for this behavior. A workaround will be added here when available.
Meanwhile we should refrain making changes in the filename from attachment section.
