Macros that need a page context aren't rendered in the header or footer

Summary

When you include a macro in the header and/or footer configured in the space's look and feel setting, this macro will show on all pages of the space.

However, macros that dynamically change based on the current page being viewed are not rendered correctly. These include:

• Attachments
• Child pages
• Page tree (when it does not define a root page for the tree)

Environment

Confluence Cloud with the new look and navigation.

Steps to Reproduce

1. Configure the space header and/or footer to have an attachments macro 

{attachments}

2. Navigate to a page that has attachments, and observe the the macro shows "No files shared here yet."

Expected Results

The attachments macro in the header / footer shows the attachments for the currently viewed page.

Actual Results

The attachments macro in the header / footer shows "No files shared here yet.
