there are some 'relatedTarget' checks below, can we dive into a shadowDOM for those as well? i don't know if there is a composedPath for them

I could see this being an issue if getEventTarget is contained in e.relatedTarget or if the e.relatedTarget is a shadowroot and contains both targets that should be ignored as well as ones which shouldn't.
For example, if someone made a Toast Container inside a shadow dom, then clicking the toasts probably shouldn't count as outside but maybe clicking between individual toasts should for some reason.

that isChildOfActiveScope might be problematic as well if the activescope is within a shadowroot

Is it weird that we call an external API with something that should be inside a shadowroot, it'd unintentionally leak shadow dom internals through our API

We don't do this in the pressEvents, though the use case is obviously a little different

I don't think these tests are going to be enough, usually overlays portal out to be a direct child of the body element, which would actually take them out of a shadowroot potentially

This can also be changed with UNSTABLE_PortalProvider

We'll need tests using the RAC Popover at a minimum

enableShadowDOM();
