Include Page Macro will not render pages with colon (:) in the title

Summary

Include Page Macro will not render pages when there is a colon ":" in the page title.
Such page titles will be interpreted as spacekey:pagetitle as per Confluence Wiki Markup

Steps to Reproduce

1. Create a page and give it a title "test title:more to follow"
2. Create another page and add Include Page Macro to it
3. In Include Page Macro enter "test title:more to follow" page title

This also happens when restoring the old version of a page with 'Page include' macro and then editing the page breaks the Macro.

Expected Results

Macro is working and page is rendered as it is within the same Space and we allow characters in page titles

Actual Results

Page will not be rendered and error is shown on the page:

Unable to render {include} The included page could not be found.

Workaround

Adding Space key before page title will allow for the page to be rendered

Note:

When the macro is edited itself - through the macro editor/browser - the macro works when you pick the page with the colon again. However, the issue seems to be recurring again.
