Highlight looping section while playing & highlight current measure differently

If I make a selection to loop I get it highlighted in yellow. As soon as I start playing the selection, the first measure is highlighted yellow and the rest of the selection loses its highlight. It would be very helpful to continue to show the entire selection highlighted in a slightly different color (e.g. light grey), while continuing to track the current measure in bright yellow.

Hence, whenever there is a selection (whether playing or not) it should be visible to the user.
