Popover Overlapping & Visibility - Incrementing Z-index?

Created by: jmealo

Popovers don't increment the z-index as they're added, this means newer popovers don't display on top of older popovers.

Use case: Using popovers for form validation error messages.

What should happen: Newer popovers are drawn on top of older popovers.

What happens now: Popovers pile up on top of each other in no particular order.
