All groups are selected when attempting to select an item from a group

Description

I am attempting to use the tags mode with groups but am not able to select more than one option at a time. When I select an option from a group, it seems to highlight/select all groups but all of the group items also disappear.

Please see the fiddle for a reproduction of this bug. Maybe this is just user error, or maybe groups do not work with objects, but from the docs it appears they do.

Thank you for any assistance.
