Form checkbox group height problem

The height of the checkbox form widget doesn’t get calculated correctly.

The problem is clearly visible when a second checkbox group is attached to the form.

I tried to reproduce the issue over the snippets platform but it seems to work there as expected so that makes me believe it may me something related to other dhx widgets which styles may override the suite ones.

Could you please, provide a complete demo or a demo link, where the problem can be reconstructed?
