Steps to reproduce:

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.

[BugBot [:suhaib / :marco/ :calixte]]

The Bugbug bot thinks this bug should belong to the 'Core::Layout: Scrolling and Overflow' component, and is moving the bug to that component. Please revert this change in case you think the bot is wrong.

Not sure what component, giving DOM a try.

The popup proposal has still features missing, so would be better to get the proposal to better shape.

Is there a reason that we want to keep this open, now that popover is being tracked in bug 1808823 ?

I don't think so. popup element isn't a thing anymore.
