Hi,

The issue is reproducible, please see example mentioned above. When the Button 1 is clicked, popover opens correctly; then, when button 2 is clicked, popover also opens correctly. The issue is reproducible only when the focus is moved with keyboard interaction (Tab, Shift+Tab), and then the popover is opened with Space/Enter - then the popover is not moved to the currently focussed button, but stays at the same.
