Popovers are broken when shown in a contextmenu event listener

[jpzwarte]

What is the issue with the HTML Standard?

If you want to use a popover for a context menu, you cannot use the contextmenu event to display the popover. The problem is that the popover is immediately light dismissed.

(not sure if this belongs in whatwg/html or whatwg/dom)

Perhaps the light dismiss behavior should be tweaked to not close any popovers that are shown immediately before in contextmenu, mousedown, mouseup, pointerdown, pointerup, touchstart, touchend event listeners?

Maybe wrap it in a setTimeout(fn, 0) so the popover gets shown after the event.

That doesn't work in Chrome, FF or Safari. Once you increase the timeout to at least 100ms, then it sometimes works. But at that point you start to have a noticeable delay.
