[legacy-next] Updating slots-controller with dispatching events

shaal commented 1 year ago

Description

This PR adds the ability to dispatch events from the cloned slots in the shadow DOM to the equivalent slots in the light DOM.

Previously, SlotsController cloned slots from the light DOM to the shadow DOM and triggered a re-render when any changes were detected in the light DOM. This update adds the capability of dispatching events specified in the cloned slots to the equivalent slots in the light DOM.

The dispatchEventsToLightDom() function has been added to the controller. When an event is triggered in a cloned slot, this function identifies the path of the event's origin in the shadow DOM. It then finds the equivalent path in the light DOM, dispatches the event to the light DOM, and resets the focus to the component that hosts the element.

This PR is intended to enhance the functionality of SlotsController, providing a more complete solution for cloning and event dispatching in a component.
