Coral Multifield Not Preventing Empty Field Submit

Hi Community!

I wonder if you ever noticed that Coral Multifield (granite/ui/components/coral/foundation/form/multifield) dialog item does not block user from submitting an empty required field. At the same time, Granite multifield (granite/ui/components/foundation/form/multifield) dialog item does the job well.

So, please, share your experience: do you have the same?

P.S. My dialog configuration with Coral widget onboard

<coralmultifield
   jcr:primaryType="nt:unstructured"
   sling:resourceType="granite/ui/components/coral/foundation/form/multifield"
   composite="{Boolean}true"
   fieldLabel="Actions"
   required="{Boolean}true">
  <field
   jcr:primaryType="nt:unstructured"
   sling:resourceType="granite/ui/components/foundation/form/fieldset"
   acs-commons-nested="NODE_STORE"
   name="./">
  <layout
   jcr:primaryType="nt:unstructured"
   sling:resourceType="granite/ui/components/foundation/layouts/fixedcolumns"
   method="absolute"/>
  <items jcr:primaryType="nt:unstructured">

   name="./f1"
   required="{Boolean}true"/>
  <field2
