/**
* @desc OverlayController is the fundament for every single type of overlay. With the right
* configuration, it can be used to build (modal) dialogs, tooltips, dropdowns, popovers,
* bottom/top/left/right sheets etc.
*
* ### About contentNode, contentWrapperNode and renderTarget.
*
* #### contentNode
* Node containing actual overlay contents.
* It will not be touched by the OverlayController, it will only set attributes needed
* for accessibility.
*
* #### contentWrapperNode
* The 'positioning' element.
* For local overlays, this node will be provided to Popper and all
* inline positioning styles will be added here. It will also act as the container of an arrow
* element (the arrow needs to be a sibling of contentNode for Popper to work correctly).
* When projecting a contentNode from a shadowRoot, it is essential to have the wrapper in
* shadow dom, so that contentNode can be styled via `::slotted` from the shadow root.
* The Popper arrow can then be styled from that same shadow root as well.
* For global overlays, the contentWrapperNode will be appended to the globalRootNode structure.
*
* #### renderTarget
* Usually the parent node of contentWrapperNode that either exists locally or globally.
* When a responsive scenario is created (in which we switch from global to local or vice versa)
* we need to know where we should reappend contentWrapperNode (or contentNode in case it's projected)
*
* So a regular flow can be summarized as follows:
* 1. Application Developer spawns an OverlayController with a contentNode reference
* 2. OverlayController will create a contentWrapperNode around contentNode (or consumes when provided)
* 3. contentWrapperNode will be appended to the right renderTarget
*
* There are subtle differences depending on the following factors:
* - whether in global/local placement mode
* - whether contentNode projected
* - whether an arrow is provided
*
* This leads to the following possible combinations:
* - [l1]. local + no content projection + no arrow
* - [l2]. local + content projection + no arrow
* - [l3]. local + no content projection + arrow
* - [l4]. local + content projection + arrow
* - [g1]. global
*
* #### html structure for a content projected node
* <div id="contentWrapperNode">
* <slot name="contentNode"></slot>
* <div x-arrow></div>
* </div>
*
* Structure above depicts [l4]
* So in case of [l1] and [l3], the <slot> element would be a regular element
* In case of [l1] and [l2], there would be no arrow.
* Note that a contentWrapperNode should be provided for [l2], [l3] and [l4]
* In case of a global overlay ([g1]), it's enough to provide just the contentNode.
* In case of a local overlay or a responsive overlay switching from placementMode, one should
* always configure as if it was a local overlay.
