Change unsupported style property pointer-events to pointerEvents

[aspiers]

The ComponentMap was causing this error:

react-dom.development.js:88 Warning: Unsupported style property pointer-events. Did you mean pointerEvents?

    in TooltipWithBounds (created by withBoundingRects())

so change it to pointerEvents.
