It's not really a bug - it's a deviation from standard behaviour that
should just be documented. I cannot imagine anyone wanting to use
DetachCurrentMessage() in that case, anyway.

But even if, we could still have some code like:
current = CurrentMessage();
FrameResized();
if (current != CurrentMessage())
        /* do whatever is appropriate */

And we can't change this, having the source and all?
