Debug UI layout not saved

The UI Layout of the debug perspective is not saved (neither during the session or on session resumption). Steps to reproduce:

• Start debug of current project
• Change UI configuration by moving panels specific to the debugging perspective. For example move "Locals" and "Expressions" to the bottom dock instead of the default right-hand dock
• Stop debugging (or close Qt Creator, reopen it and restore default session)
• Start debugging again

Expected behavior: the debugging panels should be restored to how I positioned them.

Observed behavior: the debugging panels are restored to their default position.

Maybe I'm missing something and there is an option to manually save the UI layout, in this case I apologize.
