[antoine9298]

{{dictionary|A dictionary is a *long* list of words, generally alphabetically sorted […]}}

gives you (with auto-indent)

    <abbr title="A dictionary is a <strong>long</strong> list of words, generally
    alphabetically sorted">dictionary</abbr>

so the title show html code and strange linebreak/indenting…
