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)

The search handler was being called when focusing the menuitem with the keyboard on Windows. This didn't provide a good experience and left the popup open once the search started. Ensure the popup is always shown when using the keyboard and don't trigger the search until the popup is closed.
