The flip now flips from left to right or top to bottom. Can you provide a prop to flip from left to top if there is no space in right and bottom? For example - The record appears in the list view is at the bottom right corner and popover for that last record doesn't have space at the right and bottom, so it flips to top.

Can you provide an option to display the callout in the middle of the anchor element instead of in the middle of the Popover itself?
