multitext display new input on right

Hi webix team,
Itry to add a richText on my view. but have some troubles.
When I click on add field button, a get a new input not in the right place.
I think it must go down the last input but it goes right and i cant delete it after.

here is a snippet

In order to add new fields in the correct way, you should place the Multitext view into a separate layout:

ok got it but what about minus sign for delete them?

I think labelPosition:'top' breaks the logic.
