We stop tabbing to focus on iframes on page.

This logic is reflected by the code in

src/widget-modality/js/Widget-Modality.js

        /**
         * Blocks iframes on the page from getting focused by setting their
         * tabIndex attribute to -1. The previous value of tabIndex is saved
         * so it can be restored later.
         *
         * @method _blockIFrameFocus
         * @protected
         */
        _blockIFrameFocus: function() {
            Y.all('iframe').each(function() {
                this.setAttribute('data-tabindex', this.get('tabIndex'));
                this.set('tabIndex', -1);
            });
        },

However, we should not stop focusing on iframes inside the modal. We only need to stop focusing on iframes OUTSIDE modal.
