Hello, I have noticed (https://en.wikipedia.org/w/index.php?title=Template:Languages_of_Switzerland&diff=946272656&oldid=888168862) that existence of an interwiki link in a template page, causes wrong interwiki link for *the language the interwiki link is pointing to it*, in other words it overrides the Wikidata interwiki link for that language, I don't know whether this problem is in the pages which use that template or the whole pages in the template, either the template is inserted in them or not, there is need to test it.
Steps to Reproduce:
- Add an interwiki link to a template page in en.wikipedia (preferred) the template I have linked to is the best case.
- Check the interwiki link for that language in the template pages. -- ~~~~
