Tip: NPRuntime window handle

I has found an interesting feature of a NPRuntime plug-in, when I initialize OpenGL rendering context to a particular window handle, and then I need to hide for a while and show a window in browser, using calls style.display = ‘none’ / ‘block’. As I turned out these calls are changing a window handle. This situation needs to specifically monitor, cause OpenGL context is loses.
