* - [deprecated] id (number): the item's id. This is only if
* aOptions.includeItemIds is set.
* - type (number): the item's type. @see PlacesUtils.TYPE_X_*
* - title (string): the item's title. If it has no title, this property
* isn't set.
* - dateAdded (number, microseconds from the epoch): the date-added value of
* the item.
* - lastModified (number, microseconds from the epoch): the last-modified
* value of the item.
* - annos (see getAnnotationsForItem): the item's annotations. This is not
* set if there are no annotations set for the item).
*
* The root object (i.e. the one for aItemGuid) also has the following
* properties set:
* - parentGuid (string): the GUID of the root's parent. This isn't set if
* the root item is the places root.
* - itemsCount (number, not enumerable): the number of items, including the
* root item itself, which are represented in the resolved object.
*
* Bookmark items also have the following properties:
* - uri (string): the item's url.
* - tags (string): csv string of the bookmark's tags.
* - charset (string): the last known charset of the bookmark.
* - keyword (string): the bookmark's keyword (unset if none).
* - postData (string): the bookmark's keyword postData (unset if none).
* - iconuri (string): the bookmark's favicon url.
* The last four properties are not set at all if they're irrelevant (e.g.
* |charset| is not set if no charset was previously set for the bookmark
* url).
*
* Folders may also have the following properties:
* - children (array): the folder's children information, each of them
* having the same set of properties as above.
*
* @rejects if the query failed for any reason.
* @note if aItemGuid points to a non-existent item, the returned promise is
