The keyboard drag location doesn't work for non-full screen chats

[kostub]

In JSQMessagesKeyboardController.m function

- (void)jsq_handlePanGestureRecognizer:(UIPanGestureRecognizer *)pan

which recognizes keyboard drags calculates whether to dismiss the keyboard as follows:

CGFloat dragThresholdY = (contextViewWindowHeight - keyboardViewHeight - self.keyboardTriggerPoint.y);
BOOL userIsDraggingNearThresholdForDismissing = (touch.y > dragThresholdY);

However this doesn't work if the chat view is not full screen. The issue seems to be that dragThresholdY is calculated in window coordinates while touch is calculated in the co-ordinates of the contextView as follows:

CGPoint touch = [pan locationInView:self.contextView];

I believe the correct way to do this is:

CGPoint touch = [pan locationInView:self.contextView.window];

which fixes the drag point for the keyboard.
