[Overlay] active-overlays are too controlling of neutral content #1289
Description
It look like the active-overlay element places pointer-events: none on it's content by default. This appears to be overridden by most thrown content via their open attribute that reapplies pointer-events: something.
Similarly, placement="none" currently applies height: 100vh assuming you have a "full page" modal, which isn't always true.
Review the application of both and remove where possible. When not, document the usage of content that will be thrown in this way.
