  2. Select the template at the bottom of the page and copy it (Ctrl+C).
  3. Open a random page for editing.

Actual Results:

  • Nothing is pasted, possibly an empty line.

Expected Results:

This issue is specific to this template.

Event Timeline

This happens because the template HTML starts with a <style> node (generated by TemplateStyles). When copying a template, VisualEditor stores some metadata on the first node (e.g. the name of the template). But when pasting, we remove all <style> nodes (due to T185532), which means that this node is lost and as a result we lose the entire template.
