Debugger view layout is not always saved

I have a "Locals" view to the right of the code. When I resize that and hit the "stop debugging" button and then start debugging again, then the old of the Locals view is used.

Sometimes I manage to get the layout changes to stick, but I have not yet seen a pattern.

Steps to reproduce here:

• Add a Locals view to the right of the code.
• start debugging via the big "debug" button in the mode bar
• Resize the locals view
• Hit the "stop debugger" button in the debugger toolbar. The locals view vanishes.
• Hit the "start debugging of XXX" button in the debugger toolbar. Locals view appears again.

Actual Result:

• Locals view uses sizes it had before step 3

Expected Result:

• Local view uses size after step 3
