Discrepancy in Parameters for Placement Function in Popover Component Documentation

[Yhxang]

In the v5.3 version of the Popover component, the description in the documentation regarding the placement parameter states: "When a function is used to determine the placement, it is called with the popover DOM node as its first argument and the triggering element DOM node as its second." However, based on my testing, the actual first parameter is the Popover instance, and the second and third parameters correspond to the ones mentioned in the documentation. I am unsure if this is intentional or a bug.
