Unitlist as multisuggest body does not keep the selection

Consider the following snippet: http://webix.com/snippet/8e0581f3

As you can see, I’m able to click on the component and select multiple movies.

But if I click on the component again, the selection is not shown (the values are in the component itself but is not reflected on the list).

If I click in any option, them the previous options are shown.

Would that be a bug?

Just realized, that happens with a list component as well: http://webix.com/snippet/19885614

“multicombo” supports only checksuggest and “unitlist” can not be used with it:
