Tabbed-cards, the card is not supported properly.

[MicJour]

When I use the tabbed-cards, for the headers-contained and footer-contained, the corners are square instead of having the round corners. Same thing for headers and footer.

- type: custom:tabbed-card
   styles:
     --mdc-theme-primary: yellow
     --mdc-tab-text-label-color-default: lightblue
   options: {}

   tabs:
     - card:
         type: vertical-stack
         cards:
           - type: markdown
             content: "# Météo"
             card_mod:
               class: bar

           - type: custom:layout-card
             layout_type: custom:horizontal-layout
             layout:
               width: 360
               max_cols: 3
             cards:
               - type: vertical-stack
                 cards:
                 
                   - type: markdown
                     content: "# Prévisions"
                     card_mod:
                       class: header-contained

                   - !include ../Cartes/Carte-Meteo.yaml

                   - type: markdown
                     card_mod:
                        class: footer-contained
                     content: "##  "
