Hide tabs without fields

I have dialog A (homepageNewSyntax.yaml)

label: Seiteneigenschaften
form:
  properties:
    - name: name
      $type: textField
      i18n: true
      label: Seitenname
layout:
  $type: tabbedLayout
  tabs:
    general:
      label: Allgemein
      fields:
        - name: name

• dialog B includes A at the very top of the YAML file with !include:/bn-main/dialogs/pages/homepageNewSyntax.yaml
• In dialog B I want to hide a tab that is inherited from dialog A by doing this:

!include:/bn-main/dialogs/pages/homepageNewSyntax.yaml

form:
  layout:
    tabs:
      general:
        fields: !override

or even this:

!include:/bn-main/dialogs/pages/homepageNewSyntax.yaml

form:
  layout:
    tabs:
      general: !override

• But it doesnt work

Actual
If I !override at tab level, I get an empty tab with a generated tab label like this:

If I !override at field level I get an empty tab with correct tab label:

Expected
No tab is displayed because it has no fields (like in 5.7)
