Describe the bug

In my case I have a simple Button.Group, which contains a Menu. The menu dropdown is not rendered within a portal (withinPortal={false}).

When I click on the menu dropdown instead of a menu item, the position of the dropdown changes. The same problem exists for other popovers like the Popover component.

The reason seems to be that the button group has the following styling, which effects all focused child elements:

.m_80d6d844 :where(*):focus {
    position: relative;
    z-index: 1;
}

This overrides the position: absolute; of the popover.
