Issue Summary

When copying a page (and its children pages), even even though the Cancel button is tapped during the process, the pages will still be copied to the destination.

If the pages have attachments, it will also notify watchers of the space that attachments were added to pages in the space, which could cause confusion.

Steps to Reproduce

1. As an administrator, add a watcher to Space B (the user can also do it without admin actions if needed).
2. On Space A, copy a page (with a couple of child pages so it can be easier to tap the Cancel button) and select the Space B as the location.
3. Tap the cancel button (this can be done quickly as well, without seeing the percentage of the process)

Expected Results

The pages shouldn't be copied.

Actual Results

All pages are copied and if they have attachments, will trigger notifications about the attachments being added.

Workaround

Currently, there is no known workaround for this behavior. A workaround will be added here when available
