### Feature Request

The only current way to get the parameters set by ``setBounds`` of a ``BrowserView`` seems to be to store it as a global variable at creation, and to reference that variable. Ideally, there should be a way to get this information from the created ``BrowserView`` directly with ``getBounds``, like the ``BrowserWindow``. This is particularly important if the bounds of the ``BrowserView`` has been changed by ``setAutoResize`` after creation, because the bounds no longer match a stored global variable.
