ContentReference (UiHint.Image) within IList Property List

Hello

I have a property of ContentReference decorated with UiHint.Image within a propertylist, this doesnt seem to work any more i.e. the Property does not show within Episerver. If using UiHint.Media this works just fine.

Any idea on what could be wrong, I know the image propert has recently changed and thinking this could be a bug.
