I'm not saying the back button shouldn't work. I'm saying it would be nice to have a way to do it from the webapp's UI as well.

Agreed. At this point people have been conditioned to expect the back button to lose their place or take them off the domain. So it's important to have a way in the webapp's UI even if you have the back button behaving properly.
