/**
 * An `Overlay` is a flexible floating surface, used to display transient content such as menus,
 * selection options, dialogs, and more. Overlays use shadows to express elevation. The `Overlay`
 * component handles all behaviors needed by overlay UIs as well as the common styles that all overlays * should have.
 * @param ignoreClickRefs Optional. An array of ref objects to ignore clicks on in the `onOutsideClick` behavior. This is often used to ignore clicking on the element that toggles the open/closed state for the `Overlay` to prevent the `Overlay` from being toggled twice.
 * @param initialFocusRef Optional. Ref for the element to focus when the `Overlay` is opened. If nothing is provided, the first focusable element in the `Overlay` body is focused.
 * @param returnFocusRef Required. Ref for the element to focus when the `Overlay` is closed.
 * @param onClickOutside  Required. Function to call when clicking outside of the `Overlay`. Typically this function removes the Overlay.
 * @param onEscape Required. Function to call when user presses `Escape`. Typically this function removes the Overlay.
 * @param width Sets the width of the `Overlay`, pick from our set list of widths, or pass `auto` to automatically set the width based on the content of the `Overlay`. `small` corresponds to `256px`, `medium` corresponds to `320px`, `large` corresponds to `480px`, `xlarge` corresponds to `640px`, `xxlarge` corresponds to `960px`.
 * @param height Sets the height of the `Overlay`, pick from our set list of heights, or pass `auto` to automatically set the height based on the content of the `Overlay`, or pass `initial` to set the height based on the initial content of the `Overlay` (i.e. ignoring content changes). `xsmall` corresponds to `192px`, `small` corresponds to `256px`, `medium` corresponds to `320px`, `large` corresponds to `432px`, `xlarge` corresponds to `600px`.
 * @param maxHeight Sets the maximum height of the `Overlay`, pick from our set list of heights. `xsmall` corresponds to `192px`, `small` corresponds to `256px`, `medium` corresponds to `320px`, `large` corresponds to `432px`, `xlarge` corresponds to `600px`.
 * @param anchorSide If provided, the Overlay will slide into position from the side of the anchor with a brief animation
 * @param top Optional. Vertical position of the overlay, relative to its closest positioned ancestor (often its `Portal`).
 * @param left Optional. Horizontal position of the overlay, relative to its closest positioned ancestor (often its `Portal`).
 * @param portalContainerName Optional. The name of the portal container to render the Overlay into.
