A popup displays brief content in an overlay.

/*
 * Get a memoized functional ref for use within a Popup's Trigger.
 * This is still very volatile to change as `prop.isOpen` will regularly change, but it's better than nothing.
 * This is memoized within a component as to not be shared across all Popup instances.
 *
 * This is complex because the inputs are split across three different scopes:
 *  - `props.isOpen`
 *  - `useState.setTriggerRef`
 *  - `renderProps.ref`
