"is contained in the (comma separated) list" does not allow user to select more than one value in RHDM

Issue

• When using a Guided Decision Table, if I insert a column, select "Add a condition", and use the "is contained in the (comma separated) list" operator, I can select more than one enumeration from the drop down in the data editor If I instead insert a column by selecting the "Include advanced options" box and selecting "Add a Condition BRL fragment", I'm unable to select more than one value when using the "is contained in the (comma separated) list" operator. The same applies when using the "is contained in the (comma separated) list" operator in a Guided Rule Template.
