Link previews fetch a page's OpenGraph title and description, and Opengraph::Metadata strips tags from both before the values reach the browser. When a field consists entirely of a markup tag, stripping leaves it blank, the metadata fails its presence validation, and the unfurl endpoint returns no content, so no preview is produced. Add regression tests at the model and controller layers that pin this: a title or description made only of a markup tag is stripped to blank and rejected, and the endpoint answers 204. The existing sanitize tests only cover fields that keep non-blank text after stripping, so this blank-and-rejected path was previously untested.
