Please investigate (experiment?) with implementing the <popup> element described here: https://github.com/MicrosoftEdge/MSEdgeExplainers/blob/main/Popup/explainer.md

Chrome has already indicated they intent to experiment: https://groups.google.com/a/chromium.org/g/blink-dev/c/9y-Thg9UCxY/m/_4gShWjQAAAJ

Motivation: when creating web components for a design system, I often run into problems with overflow. For example a tooltip or popover that is linked to an element that is inside a scroll container. By default, that element would appear inside the scroll container. There is currently no standard way for content to appear outside of the scroll container. <popup> would fix that omission.
