If you’re viewing a tag and you switch to a different tag via the sidebar or the tags dropdown, after expanding the info section of the tag page via the wrench button, the info section keeps showing the previous tag's details instead of the new one.
This happens because the tag info section makes an ajax request to load the tag's details, and this request is made inside the `didInsertElement` hook which is only fired once when the component is rendered. To fix this, we need to set the result from the ajax request to null and add a `didUpdateAttrs` hook to trigger another request to load the info of the new tag.
