Readonly parameter can be pypasses wi to multivalue control

[Christ0phH]

System: -Azure DevOps Server 2019.1.1 (Version Dev17.M153.5) Using

• Chrome 80.0.3987.122 -FireFox 68.5.0esr
• Multivalue control 2.2.26 (Latest)

When using the xml based control contribution

<ControlContribution Label="Somemultivalues label" Id="ms-devlabs.vsts-extensions-multivalue-control.multivalue-form-control">
                <Inputs>
                  <Input Id="FieldName" Value="Somemultivalues" />
                </Inputs>           
</ControlContribution>

and defining a readonly state e.g. in a state definition or transition

<FIELD refname="Somemultivalues" >
    <READONLY for="[Project]\AUserGroup"/>        
</FIELD>

**

• The field still can be changed by the "AUserGroup"
• The error message "The value for field 'Somemultivalues' must be the same as the original value." is displayed when picking something more and other then the former value
• ! But when picking NOTHING saving the change by "AUserGroup" is possible! -- Parameter "CANNOTLOSEVALUE" is not helping
