-  when they are resized explicitly by a `CoreResizer`, or when the window has been resized.
-  Note, the `core-resize` event is non-bubbling.
-
-  `CoreResizable`'s must manually call the `resizableAttachedHandler` from the element's
-  `attached` callback and `resizableDetachedHandler` from the element's `detached`

-  Elements that cause their children to be resized (e.g. a splitter control) or hide/show

-
-  `CoreResizer`'s must manually call the `resizerAttachedHandler` from the element's
-  `attached` callback and `resizerDetachedHandler` from the element's `detached`
-  callback.
-
-  Note: `CoreResizer` extends `CoreResizable`, and can listen for the `core-resize` event
-  on itself if it needs to perform resize work on itself before notifying children.
-  In this case, returning `false` from the `core-resize` event handler (or calling
-  `preventDefault` on the event) will prevent notification of children if required.
