Feature Request: Support Docked Window Size Recovery After Closing and State Save

[strentler]

• Steps to reproduce:
  • 1. Dock a window
  • 2. Change the width of the window by increasing its size
  • 3. Close the window while in docked state
  • 4. Store the state
  • 5. Restore the state
  • 6. Open the closed window again
• Result:
  • The window is restored with some default width
• Expected:
  • The window is restored with the same size before it was closed
• Notes:
  • If you just close the window and open it again without storing and restoring the state in between, the window size is preserved
  • I observe the same behavior in the demo application
  • I used the latest master
