LGTM.com - false positive: "Duplicate HTML element attributes" caused by valid Django template tags

[pirate]

Description of the false positive

<form id="changelist-form" method="post"{% if cl.formset and cl.formset.is_multipart %} enctype="multipart/form-data"{% endif %} novalidate>{% csrf_token %}

This is valid Django template HTML with no duplicate attributes, however LGTM reports it as having duplicate tags due to it seeing {% and %} appear multiple times in a single opening tag.
