Action Menu Inside Popover

A real-world "more options" pattern: a dropdown menu (auto popover) with a nested "Share" button that opens a sub-panel. In Chrome 133, clicking the nested button no longer re-invokes (closes + re-opens) the parent dropdown.

The nested Share button is both inside the dropdown AND has popovertarget="sharePanel". Pre-133: clicking it would briefly close the dropdown (re-invoke flicker). Chrome 133: the nested invoker check prevents re-invocation of the parent; only the sub-panel opens.

Try it — open the menu, then click Share
