There should be no empty headers like <h2 id="views-ajax-title"></h2> which appears in admin/structure/views/view/test (after you create the View "test")
I pulled out more html than was needed, but thought it might be useful for context.
<div id="views-ajax-popup" class="form-wrapper"><h2 id="views-ajax-title"></h2><div id="views-ajax-body" class="form-wrapper"><div class="message">Click on an item to edit that item's details.</div></div></div><input type="hidden" name="form_build_id" value="form-kyGXhR5hTAenhx3lMUNa51Hel59bJfbe0MURpzc91m4" /><input type="hidden" name="form_token" value="DOCx1Kp8QMrJ67rDfMhwJM28NPaekHB_iYs_Z53hoRA" /><input type="hidden" name="form_id" value="view_edit_form" /><div class="form-actions form-wrapper" id="edit-actions"><input type="submit" id="edit-actions-submit" name="op" value="Save" class="button button-primary form-submit" /><input type="submit" id="edit-actions-cancel" name="op" value="Cancel" class="button form-submit" /></div></div></form></div><div id="views-preview-wrapper" class="views-admin clearfix"><form class="view-preview-form view-form" action="/admin/structure/views/view/teest/preview/page_1" method="post" id="views-ui-preview-form" accept-charset="UTF-8"><div><div class="form-item form-type-checkbox form-item-live-preview">
