Scroll pocket may obscure web content in fullscreen mode

Reviewed by Tim Horton.
In WebViewImpl::updateScrollPocket(), a scroll pocket is created when
`needsTopViewForFullScreenTitlebar` is true. In certain cases, in fullscreen
applications, the scroll pocket of a webview in an NSScrollView may have a
non-zero
height and obscure the web content. Speculatively fix this bug by making
`needsTopViewForFullScreenTitlebar` false when the webview is not the document
view
of an NSScrollView.
