You can use "document_src" and (maybe "PrincipiaSearchSource").
Both are protected by "View management screens".

I found this out with my "DocFinder" product:

I fear that is because Page Templates bind the "traversal_subpath"
(like Python Scripts do).
Unlike with Python Scripts, they do not provide a way to customize
this behaviour.

I do not know why they bind "traversal_subpath". I think, it was
accidental (because the inherited "Script" does it).
Maybe, you file a collector report.

The effect of binding "traversal_subpath" is that URL traversal
stops at the object. The remaining URL path goes to the "traversal_subpath".
This is lost for Page Templates, as it is not exposed (you see, it feels
like a bug).
