Loads a XUL overlay and merges it with the current document, notifying an
observer when the merge is complete.
NOTICE: In the 2.0 timeframe this API will change such that the
implementation will fire a DOMXULOverlayMerged event upon merge
completion rather than notifying an observer. Do not rely on this
API’s behavior not to change because it will!

url | The URL of the overlay to load and merge |
observer | An object implementing nsIObserver that will be notified with a message of topic "xul-overlay-merged" when the merge is complete. The subject parameter of |observe| will QI to a nsIURI - the URI of the merged overlay. This parameter is optional and may be null. |
These attributes correspond to trustedGetPopupNode().rangeOffset and
rangeParent. They will help you find where in the DOM the popup is
happening. Can be accessed from chrome only, and only during a popup
event. Accessing any other time will be an error.
