= FileAttachedEvent behaves differently when using <<Include()>> =

I'm using the [[ParserMarket/matplotlib]] parser to generate images dynamically
(only when the matplotlib code has changed).
After the image(s) are generated, `send_event(FileAttachedEvent())` is called to
index the generated images. The indexing works fine when the page (say it is called MplPage) 
with the matplotlib code is rendered directly. I check the
indexing by doing a Full``Search(), which brings back the attachments on MplPage.

If I repeat the above by including Mpl``Page with the `<<Include()>>` macro within another page,
the images are no longer indexed.

== Steps to reproduce ==

 1. Create sample page Sample``Page with following content
 {{{
<<Include(/subpage)>>
 }}} 
 1. Create /subpage where the parser is called
 {{{{
{{{#!xap
Hello world!
}}}
 }}}}
 1. Goto /subpage (check if attachment test-indexing.txt has been created)
 1. Search for text-indexing.txt, should return /subpage with attachment
 1. Goto /subpage and delete test-indexing.txt (without reloading page)
 1. Goto Sample``Page (includes /subpage and recreates test-indexing.txt)
 1. Search for text-indexing.txt, /subpage with attachment no longer found
