Include macro within a box macro doesn't show the page as "included"

When I have the following piece of code in a page:

{{include document="Main.Test" context="current"/}}

the editor shows that Main.Test is included in the current page on the right side (which is very helpful). It would be great to have this extended even if the include macro is within another macro:

{{box}}{{include document="Main.Test" context="current"/}}{{/box}}

This unfortunately does not show the Main.Test page as included in the current page.
