libview: Save/restore context when getting colors for a  different state different state

libview is using the style context to get colors for a different state of the widget without saving/restoring the context from its draw call. This can trigger an invalidation and a redraw. And since this is happening from the draw call there is a redraw loop resulting in constant high CPU usage.

This is happening for example when selecting text or if some search result is visible on the current page.
