Toolbar: Default selectable borderless background is drawn behind "URL box"

[pocmo]

If an URL box background view is set then the selectable borderless background of actions may be drawn behind it.

The reason for that is that the default implementation draws on the closes background available (because the ripple exceeds the view's bounds). In this case it is the background of the BrowserToolbar which is always behind the URL box.

On Stackoverflow some seem to work around that by introducing a wrapper view to draw the ripple effect on. But I would like to avoid adding another view just for that reason. Another option may be to create a customized ripple effect that stays inside the bounds.
