I have a MultiSelect Combobox that I need to set to readOnly (disabled is not an option in my specific application).

It seems that while ReadOnly prevents new selections from being made it still allows users to click the "X" and remove selections from the combobox.

here is a filddle showing the problem: https://fiddle.sencha.com/#view/editor&fiddle/3750

if this is not a bug then what should I be doing to ensure that my "read only" combo box does not allow the user to make any changes to the selections?
