An outer div has been added to the internal HTML of the overlay element to allow for independent flipping of the content. Flipping will invert the `scaleX` value of the transform property for the style of the element. By setting the value `overlayContentFlipped: true` in the OSD config we can flip the content in the opposite direction to the overlay, but by setting this to false we can flip the content along with the overlay. This allows for some people who are using images in their overlay to flip the images along with the overlay.
