Michel Weststrate c9b08695d5 Make sure out-of-contents rendering is supported in Sandy
Summary: For RN Debugger an ugly hack is used that roars its head now again; to make sure that the embedded debugger state isn't lost when switching to a different plugin, the chrome devtools are rendered _outside_ the domNode where they should normally appeared, and made invisible rather than removed when becoming invisible. Since at this moment this is the only place where we apply the trick, figured for now to condone it, rather than making a neater abstraction out of it (or kiling it all together)
