Bug 1518932 - Convert menulist to custom element r=paolo This custom element replaces XBL <content> usage by directly prepend the two needed child nodes when the element is connected. This is doable because - There isn't any direct access of child nodes under <menulist>. Everyone seems to access via .menupopup, which is usually the only child. - We don't need to move the children under <menulist>. If we need to and if the child is a <xbl:children> (which could happen if <menulist> is inside an XBL <content> that just get cloned to the document), the layout will get very confused and crash (see finding in bug 1514926) Differential Revision: https://phabricator.services.mozilla.com/D16149
