Is there a way to check if the active window has IntelliSense popup open?

Question

Is there a way to check if the currently active window has IntelliSense popup open in a Visual Studio Extension?

I want to abort the TextChanged event handler execution if IntelliSense is open.

You can call Microsoft.VisualStudio.Language.Intellisense.ICompletionBroker.IsCompletionActive(textView);
