FlxState transparent background and openfl next

[Thomas Bernard]

I have an FlxState in witch I need to have a transparent background (because I draw, in some offscreen zone, elements that would be used by an overlay camera. Like in : http://haxeflixel.com/demos/FlxCamera/ exept that I want my overlay camera to have a complete transparent background rather than a black semi-transparent one).

When I use openfl legacy, this render perfectly. But as soon as I use openfl next, my FlxState with a transparent background (bgColor=0x00FFFFFF) render as completely black...

If I set my backdround as full white ( bgColor=0xFFFFFFFF) this work as expected (I can see my FlxState elements) exept that, of course, my overlay camera has a white background that mask what is behind.

So is there any way to fix this issue and use a transparent background in an FlxState with openfl next? 

Currently I fixed this by using bgColor=0x01FFFFFF, which, in practice, is not distinguishable. But it would be better and cleaner to be able to use a fully transparent background with bgColor=0x00FFFFFF...
