withPosition not working correctly inside a ShuffleboardLayout of type BuiltInLayouts.kList

[smoser]

Describe the bug
withPosition is being honored inside a ShuffleboardLayout of type kList.

To Reproduce
Steps to reproduce the behavior:

1. create a new project and put the following into src/main/java/frc/robot/Robot.java

package frc.robot;

import edu.wpi.first.wpilibj.TimedRobot;
import edu.wpi.first.wpilibj.shuffleboard.ShuffleboardTab;
import edu.wpi.first.wpilibj.shuffleboard.BuiltInWidgets;
import edu.wpi.first.wpilibj.shuffleboard.BuiltInLayouts;
import edu.wpi.first.wpilibj.shuffleboard.Shuffleboard;
import edu.wpi.first.wpilibj.shuffleboard.ShuffleboardLayout;

public class Robot extends TimedRobot {
  private ShuffleboardTab shuffTab = Shuffleboard.getTab("MyTab");

  public void addTab(String name) {
    ShuffleboardLayout myGroup = shuffTab.
        getLayout(name, BuiltInLayouts.kList).withSize(1, 3);
    myGroup.add("Enable", true).withWidget(BuiltInWidgets.kToggleSwitch).
        withPosition(0, 0).getEntry();
    myGroup.add("Invert", false).withWidget(BuiltInWidgets.kToggleSwitch).
        withPosition(0, 1).getEntry();
    myGroup.add("Rotations", 0).withPosition(0, 2).getEntry();
    myGroup.add("Target", 1).withPosition(0, 3).getEntry();
  }

  @Override
  public void robotInit() {
    addTab("group 1");
    addTab("group 2");
    addTab("group 3");
  }

  @Override
  public void autonomousPeriodic() {  }

  @Override
  public void teleopPeriodic() {  }
}

2. Run project
3. Open shuffleboard

Expected behavior
I expected each "group" to have the indicated order of widgets.
What happens is that the groups differ seemingly randomly.
I expected that widgets order inside would be 'Enable', 'Invert', 'Rotations', 'Target' based on the use of withPosition.

Note that this does work with kGrid.

If this is a problem in shuffleboard itself rather than the API, perhaps this issue should be moved to the shuffleboard repo?
