oj-c-select-multiple component behaves different from the cookbook

Summary:

Hi,

I am implement oj-c-select-multiple component, but when i select any values from drop-down first and then try to search other values are typing it in component then it is not checking the values.

1. Below is the cookbook example for oj-c-select-multiple (https://www.oracle.com/webfolder/technetwork/jet/jetCookbook.html?component=selectMultipleCorepack&demo=states

as per above image after we select 2 values (Chrome,Firefox) we can start typing in the component and filer any value. But when i am implementing the same in my app it is coming up as below and if i try to filter values for ex. Opera/Safari it is not coming up.
