Status: RESOLVED FIXED

+++ This bug was initially created as a clone of Bug #1583377 +++

Similar to xul:page, I'd like to stop using non-window xul root elements in order to make migration to html roots easier.

There are only two consumers of this element in m-c: https://searchfox.org/mozilla-central/search?q=%3Cwizard&path=.

• There are two places in the platform that treat wizard specially https://searchfox.org/mozilla-central/search?q=%3A%3Awizard&path=. One is just because it's a root element, and the other is an accessible place that I believe can be fixed by using [role=dialog] on the new root: https://searchfox.org/mozilla-central/rev/f1e99da78fe6c3c68696358dac06aed90f8112d3/accessible/generic/RootAccessible.cpp#89.
• There are also hits in JS such as document.documentElement.rewind, document.documentElement.cancel, etc (https://searchfox.org/mozilla-central/rev/f1e99da78fe6c3c68696358dac06aed90f8112d3/toolkit/content/widgets/wizard.js#472) which depend on the documentElement being the <wizard> custom element with these properties. Those calls should be able to switch to this within the wizard CE and to a reference to the DOM node from any external callers (if any).
• Some of the CSS (when it's treating wizard as a root element) can be removed as well: https://searchfox.org/mozilla-central/search?q=%5Ewizard&regexp=true&path=.css.
