Add Page -> Parent Page field not updating when page is added from a parent

When adding a page from another page, the Parent Page input from the Add Page modal does not update it's value if change. The change are reflected when creating the page, but there is no way for the user to know that unless he goes ahead and click Continue.

Please ignore the closing and opening. Poor clicking on my part.
