Comment 1 for bug 963482

Re: the settings pages... it's not specific to those, it's every template that inherits from modal_form.html when viewed as a static page rather than loaded dynamically as a modal. The culprit is in this line:

https://github.com/openstack/horizon/blob/master/horizon/templates/horizon/common/_modal_form.html#L1

Essentially, the modal class should only be applied when the form is loaded via ajax, and the static_page class should contain a complete set of styles for appropriately displaying that content without the modal class.
