I also renamed migration-dialog.[js|html|css] to migration-dialog-window.[js|html|css] to make it clearer that those resources are for when the wizard is being shown in a separate window. I also updated the documentation to reflect this. Differential Revision: https://phabricator.services.mozilla.com/D169014
