Popover styleType does not apply the style

[dasadhanala]

The background color of a Popover component is not altered by applying a styleType prop to it.
(If styleType is meant to alter the background color of the popover in this manner.)

I tried add a background color to the popover component, but that was only applying to the inner div element, as shown below:

It would be extremely helpful if a prop existed that could alter the color of the popup's skin.

To get around the problem, we're applying a background color to the root close wrapper, which is done by custom styling. However, if the popup component were to undergo any changes, this could cause problems.
