Is the linter supposed to flag cases where no text appears between double brackets? E.g. on nl:Station Antwerpen-Centraal, the top of the infobox is an image, which is wrapped between font-tags.

Image captions are also affected, although maybe we don't have checks for whether the image caption is absent. For that scenario, we don't need to flag a lint error.
Are you sure? Captions shouldn't render differently, and if they do, I suppose that would be a different linter category.
Hmm ... you are right. I am sure I tested it, but, clearly I botched my testing there! I'll update my linter code to not flag image captions. Thanks for the bug report! :)
