Are you sure we need this? I create zero rect views all the time.

Zero-rect views are fine. I wanted to change this too to match the window it's
going into. It probably doesn't matter anyway; the docs from -setContentView:
say that the view is resized to match the window size.

will this be visible?

No, I checked. The bubble's faded to zero opacity at this point.
