Resize Observer

<ahi-resize-observer> | AhiResizeObserver

The Resize observer offers a thin, declarative interface to the ResizeObserver API.

The resize observer will report changes to the dimensions of the elements it wraps through the ahi-resize event. When emitted, a collection of ResizeObserverEntry objects will be attached to event.detail that contains the target element and information about its dimensions.
