[carlreinke]

Steps to reproduce

1. Load System.Windows.Forms, Version=9.0.0.0
2. Decompile System.Windows.Forms.Control.PerformLayout(LayoutEventArgs args).
3. In the code pane, right-click on OnLayout and click "Analyze".
4. In the "Analyze" pane, expand "Used By".

Expected behavior

"Used By" should include the method that was just decompiled.

Actual behavior

"Used By" is empty.
