When viewing Special:ListProperties ([[ https://www.wikidata.org/wiki/Special:ListProperties?uselang=gd | language set to Gaelic ]]),, all properties shown are rendered in the same way and labelled as the user's language, regardless of whether they're actually in that language or not. all properties shown are rendered in the same way and labelled as the user's languageFor example, regardless of whether they're actually in thatwith the [[ https://www.wikidata.org/wiki/Special:ListProperties?uselang=gd | language or not.e set to Gaelic (gd) ]] -
`<li><a title="Property:P27" href="/wiki/Property:P27"><span class="wb-itemlink"><span class="wb-itemlink-label" lang="gd">country of citizenship</span> <span class="wb-itemlink-id">(P27)</span></span></a></li>`

Note that both use `lang="gd"`, although P27 is using the English (en) label, and P30 is using the correct Gaelic (gd) label.
When seen elsewhere, eg [[ https://www.wikidata.org/wiki/Q6198115?uselang=gd | on an item ]], fallback labels are correctly shown as `lang="en"`:
`<div class="wikibase-statementgroupview-property-label" dir="auto"><a title="Property:P27" href="/wiki/Property:P27" lang="en">country of citizenship</a><sup class="wb-language-fallback-indicator">Beurla</sup></div>`
