Ranges not updated in the dock widgets upon undo/redo.

Requirements

• I searched through the issues if the issue already exists

Steps to reproduce

1. Create a plot with two ranges and add a xy-curve (or use the projecmulti-range-bugs.lml
2. Change the range in the dock
3. Perform undo

Expected

The previously used range should be shown in the combobox upon undo.

Observed

Range is not properly updated in the combobox
