What happened to the faded BG when entering a symbol?

I have used Flash for over a Decade, but Im new to animate. I can´t seem to figure how to get the faded BG I used to get when going inside a symbol. It seems the functions is either turned off by default (why?) or removed completely. This was a really important feature to both know what's inside a symbol and also draw comfortably without too much interference from the BG or other characters or even other parts of the character. I am going crazy here, anyone else talked about this before? any plans relevant to adding this back? do I have to resort to adding a white solid with alpha to every symbol in a guide to get this effect? Man, Animate is even more frustrating than Flash. This adds to a growing list of things I highly dislike about Animate.
