Improve peek behavior and fix a few bugs in PanelView
- A single tap on the bar peeks and then dismisses it a again.
- Wait for the peek until the layout has happened.
- Add logic to only peek if user is not flinging.
- Fix a few bugs with panel holes (onExpandingStarted/Finished not
called correctly.
