In Lightning Experience, my Flow Screen with 'Show Header' set to false still shows the header.

I am launching the flow from a Quick Action.

'Show Footer' works as expected and I am able to override the navigation with Lightning Components

Is anyone aware of any issue or limitation? I can see this being documented somewhere as "Show Header currently is not supported for quick action distributed flows"
