Composer Pro doesn't preview the Conditional Renderer component properly. Anything in the renderer is forced to about half the width of the screen, so I can't see how it's actually going to lay out (all of my components are set to Grow to Full Width.)

In the Composer screenshot, you can see my components at the top going full-width as intended, but the exact same components in the Renderer show up in a narrow column. The display of those same components is correct, however, when I preview in the Debugger App, but still, it's just very hard to figure out how to lay out my screen when I can't see it until I push to the phone.

Since the Conditional Renderer doesn't have any layout properties of its own, I don't see a way to fix this. Can you guys force the Renderer to go 100% width in Composer? Or allow it to have layout properties?
