GameGUI windows cannot be opened in the editor.

[DreamyCecil]

For some reason windows from patched GameGUI (player appearance, console etc.) cannot be opened in any Serious Editor (vanilla or patched). And this isn't an issue with the patched editor because vanilla GameGUI windows open just fine.

Tested configurations

• Patched WorldEditor:
  • CustomMod = 1 - doesn't work (patched mod libraries)
  • CustomMod = 0 - works (vanilla mod libraries)
• Vanilla WorldEditor:
  • CustomMod = 1 and FullAppIntegration = 0 - works (still using vanilla mod libraries due to integration limitations)
  • CustomMod = 1 and FullAppIntegration = 1 - doesn't work (patched mod libraries)
  • CustomMod = 0 and FullAppIntegration = 1 - works (vanilla mod libraries)
