Display the content view in a popup window anchored to the bottom-left corner of the anchor view offset by the specified x and y coordinates. If there is not enough room on screen to show the popup in its entirety, this method tries to find a parent scroll view to scroll. If no parent scroll view can be scrolled, the bottom-left corner of the popup is pinned at the top left corner of the anchor view.
If the view later scrolls to move anchor to a different location, the popup will be moved correspondingly.
