To expand a bit, WebViewPlugin is a WebPlugin implementation that forwards drawing and input event handling to a separate WebView, to allow us to draw plug-in placeholders in HTML. The inner WebView is by design completely independent from the outer one (from the point of view of the outer one, it's just a plug-in), so it shouldn't be a problem that we call layout() on the inner one during paint() in the outer one. WebPlugin also doesn't have a layout() method, so we can't call layout() on the inner WebView when the outer one is being layouted.

Is the crash caused by the two RenderViews somehow sharing graphics layers? If so, maybe that's what we should prevent.
