This logic is an improved version of the same logic inside the Popover component

const top = Math.min( selectedBCR.top, lastSelectedBCR.top );
const right = Math.max(
selectedBCR.right,
lastSelectedBCR.right
);
const bottom = Math.max(
selectedBCR.bottom,
lastSelectedBCR.bottom
);
const width = right - left;
const height = bottom - top;

return new window.DOMRect( left, top, width, height );
},
ownerDocument: selectedElement.ownerDocument,
} ),
[ selectedElement, lastSelectedElement ]
);

if ( ! selectedElement || ( bottomClientId && ! lastSelectedElement ) ) {
return null;
}

const anchorRef = {
top: selectedElement,
bottom: lastSelectedElement,
};

return (
