Item popups within the map view may show multiple field. Currently, their order seems to be not related to the list in the select clause. Example:
```lang=sparql
#defaultView:Map{"hide":"?geo"}
select ?image ?item ?itemLabel ?pobLabel ?viewer ?geo
where {
# occupation: economist
?item wdt:P106 wd:Q188094 ;
# with PM20 id
wdt:P4293 ?pm20Id ;
# with place of birth
wdt:P19 ?pob .
# geo coordinates for pob
?pob wdt:P625 ?geo .
# optional image
optional { ?item wdt:P18 ?image . }
# viewer link
bind(substr(?pm20Id, 4, 4) as ?numStub)
bind(substr(?pm20Id, 4, 6) as ?num)
bind(uri(concat('http://dfg-viewer.de/show/?tx_dlf[id]=http://zbw.eu/beta/pm20mets/pe/', ?numStub, 'xx/', ?num, '.xml')) as ?viewer)
# add labels
service wikibase:label { bd:serviceParam wikibase:language "[AUTO_LANGUAGE],en, de, fr, es, nl, pl, ru". }
}
```
This results in the non-sensical sequence:
- ?pobLabel
- ?viewer
- ?image
- ?item/?itemLabel
in the the popup.
Users should be able to enforce a certain field sequence via the select clause.
