WinformsHost Airspace/Overlap issue still present in 4.5?

Hi all,

I have a question in regards to using WindowsFormHost element with overlapping controls.

I know that in the past this was indeed an issue and I was wondering if it is still present.

According to this blog, the issue is supposed to be resolved in the framework 4.5:

But if I read from MSDN for the framework 4.5 I see the following:

My initial test seems to tell me the problem is still here, but maybe im not using it correctly.

Thanks for helping me clarify this.
