overlays will not close previous ones so that they don't conflict and there can essentially be unlimited modal navigations. Done by passing the modal data to each modal using a global hook instead of relying on local data for each.
When navigating to a new path, it closes all modals.
On CollectionOverlay, when opening a new details modal overlay, it closes the previous using a custom ShowDetails handler.
This isn't the cleanest approach, but offers the greatest flexibility in the future
