Fields in form layout is in full size

Steps to reproduce

1.  Create form with form or declarative layout

   form:
     properties:
       salutation:
         label: Salutation
         $type: textField
       firstName:
         label: First Name
         $type: textField
       lastName:
         label: Last Name
         $type: textField
     layout:
       $type: form
       #$type: declarativeLayout
       #template: /hello-magnolia/dialogs/declarative-dialogs/test.html
   

1.  If use declarative, use tag <vaadin-form-layout> as document mentions:

   It is recommended that Magnolia properties be nested inside a <vaadin-form-layout> tag. If you insert a Magnolia property inside a <vaadin-vertical-layout> tag, the component will not be rendered as nicely.

1. Check the field's width

Expected results

Fields should be rendered nicely

Actual results

Fields are full width and not look nice
