I was in 1P on my iPhone and it went to sleep. I pressed the home button and used Touch ID to log into the phone. The 1P screen appears asking me to use Touch ID. I don't want to be in 1P, it's just the last app I was in. I press the home button and the 1P screen appears again. Normally if unlocking the phone takes me to an open app, I can simply press the home button to take me back to the browser. It's a little odd behavior, different from expected, but obviously not difficult to get around.
