Gets the following error:
/w/index.php?title=Topic:Sf13ilzrrecc7k1s&action=edit-topic-summary Flow\Exception\InvalidInputException from line 208 of /srv/vagrant/mediawiki/extensions/Flow/includes/Block/Block.php: Template is not defined for action edit-topic-summary in Flow\Block\TopicBlock
This occurs because the javascript side does a full refresh of the topic, but the nojs side only needs and uses the topic summary information.
