I forgot about that use case. I paste into and copy from the address bar all the time. But I still get myself sideways because I treat it like any other text box, and end up de-selecting the URL and having to try again!
You'd think after so long, I'd get used to the behavior and just single-click it. But apparently Pavlov would have me culled from his experiment :)
Time doesn't matter, because you probably interacts with many more normal text fields than browsers URL fields. And since they look the same, and act mostly the same, you won't learn to handle it correctly.
