If you insert a template with TemplateStyles and add a file inline in the same paragraph, the paragraph breaks with a <link> being a separator between two faulty paragraphs. If no <templatestyles> is present, this type of layout breaks into one paragraph and a file.
This is not a good example of wiki text markup, but since it doesn’t cause issues without TemplateStyles it’s probably better to fix this.
