Create an MDI application with a ToolWindow to the left and an AutoHide ToolWindow at the bottom and a WebBrowser in a document.  Click on the ToolWindow to AutoShow.  Notice the WebBrowser draws over any portion of the ToolWindow that overlays the WebBrowser.

Yes that is a well-known "airspace" issue with WPF in general (nothing related to our controls) where interop controls like WebBrowser always render on top of WPF content in the same Window. 

We have some workarounds via options in place that you can activate.  Please see this documentation topic for details.
