ReadOnly Property not being respected on SymbolLabel

I want to restrict the user from being able to edit the symbol label on my symbol when the label is double clicked. In my symbol model I have set the label property ReadOnly = true but I can still edit the label after doing this. This is also the case in the SymbolFactory Example where the symbol label for "Hello World" is set to be ReadOnly but you can still edit the symbol. What am I doing wrong?
Thanks
