Smart Fields drop down of page names is inconsistent over whather it shows the space name or not

Use the Macro Browser to enter the viewdoc macro, and enter 'tes' into the Page Name field.

The quick search drop down shows the page name suggestions, but some pages are shown with the space name, some without.

This can be very confusing when trying to find a particular page which has a similar name to many other pages.

It also looks ugly - shouldn't the space name be after the page name?
