Thread:VisualEditor/Feedback/HTML output from template leaked into wikitext

[ Is this a known bug?] &lt;ref>&lt;span style="display: none;" class="Z3988" title="..." data-ve-ignore="true"> &lt;/span>&lt;/ref> Short explanation: The German template de:Vorlage:Internetquelle outputs a COinS record. This is basically an empty &lt;span> element with a long title attribute. For some reason this &lt;span> element made it into the wikitext.

Expected wikitext: &lt;ref>&lt;/ref> Unfortunately I can't tell you how to reproduce this since it was reported by an other user, see de:Wikipedia:Fragen zur Wikipedia.
