Is there a reason why |is_fullscreen| is not copied?

[liberato (no reviews please), 2017/05/24 21:21:07]

because it's error-prone.  :)  good catch.

i really don't like this pattern.  too bad that one can't "operator|=() =
default" with base::Optional supporting |= .

+    routing_token = other.routing_token;
+
+  return *this;
+}

+}  // namespace media
