Popup window will be drawn at a incorrect position when using PopupWindow.Show()
How to reproduce:

2. Click Tools > Popup 00
3. Observe where the pop up is drawn
4. Click Popup MyWindow 00
5. Observe where the Popup is drawn
Expected result: Popup 00 is drawn at the top left corner of the Unity window. Popup MyWindow 00 is drawn at the top left corner of MyWindow window.

Resolution Note (2021.2.X):
Restoring this legacy behavior has caused other regressions. The correct solution is either to only call PopupWindow.Show() inside OnGUI() calls as shown in the documentation: https://docs.unity3d.com/ScriptReference/PopupWindow.html
Or to convert the screen space coordinate you desire into the current GUI space using GUIUtility.ScreenToGUIPoint()
