Relabel ask templates test

Trying to understand how the Property:Has preferred property label interacts with #ask queries with plainlist+template, as reported in issue: https://github.com/SemanticMediaWiki/SemanticMediaWiki/issues/3548

Regular query

(edit to view its source)

Page	occupation ᵖ	occupation ᵖ	Occupation	Ocupación	overriden
Alexey Gorobecky	General	General			General
Anastasia Zhyrkova	Student	Student			Student
... autres résultats

Plainlist + template + named args

template

From Relabel ask templates test/ask_template:

<hr>
* Page({{{Page}}})
* P106({{{P106}}}): FAILS
* P106@es({{{P106@es}}}): FAILS
* occupation@en/fr({{{occupation}}}): ok
* ocupación@es({{{ocupación}}}): FAILS
* overriden({{{overriden}}}): ok

Questions:

• But why does it work only with the en/fr parameter-name, and not with original property name P106?
• Shouldn't it work also with property's page name? (or else, one edit breaks all existing #ask queries).
