You're right that we use the dynamic frame for gestures, but we use the lexical frame for almost everything else.  Calling the dynamic frame the "active frame" is likely to confuse people into screwing up other uses.

>How about adding a new method like activeFrameIsProcessingUserGesture and use it to test active frame's user gesture. Otherwise can we use ScriptController::anyPageIsProcessingUserGesture() to test whether any frame is prcessing user gsture.

I don't understand why we need these two APIs.  Can you explain why we need to make these distinctions?  It seems like clients just want to know if we're processing a user gesture.
