Linking Page to Sprint Report not working with full URL

Steps to Replicate:

1. Create an Application Link between JIRA and Confluence;
2. Try to link a page in the sprint reporter by pasting the page URL.

Actual Results:

When adding an existing Confluence's page to a Sprint Report, if I use the full URL, it doesn't work. The error message is "No matches".

However, if I search for the page name, it works.

Expected Results:

The page should be linked successfully.

Workaround:

Search for the page name instead of pasting the URL.

Notes:

If this is an expected behavior, a note mentioning this in the following doc would be great:

Tested using JIRA 6.3.9, Agile 6.6.51 and Confluence 5.6.3.
