Tabbed Card tabs not working in 2025.5

Configuration Frontend

I’ve been running for a long time using the custom tabbed card, particularly on status devices to save space. But since upgrading to 2025.5 the tabs no longer function or display. Here’s some sample code that’s been running fine previously:

type: custom:tabbed-card
styles:
  --mdc-typography-button-font-size: 11px
  --mdc-tab-text-label-color-default: gray
  --mdc-tab-stacked-height: 155px
tabs:
  - attributes:
      label: Weather
      icon: mdi:weather-cloudy
    card:
      type: horizontal-stack
      cards:
        - type: custom:weather-card
          entity: weather.kith_daynight
          name: Ithaca
          current: true
          details: true
          forecast: false
          hourly_forecast: false
  - attributes:
      label: Radar
      icon: mdi:radar
    card:
      type: horizontal-stack
      cards:
        - type: 'custom:weather-radar-card'
          center_latitude: !secret latitude
          center_latitude: !secret latitude
          data_source: RainViewer-Rainbow
          frame_count: 50
          frame_delay: 200
          restart_delay: 1200
          map_style: voyager
          show_marker: true
          show_playback: true
          show_recenter: true
          show_range: true
          show_scale: true
          show_zoom: true
          zoom_level: 8
          view_layout:
            grid-area: footer

Now every page that has a tabbed component gets blown up with the icons stacked vertically and filling the display port. If I comment out the icons in the attributes the page then displays properly, but I get no tab bar. You get the first “Weather” component displayed, but no tab that allows you to click and see the “Radar” component. It doesn’t matter what component is displayed on any of the tabs, it’s always the same issue. Has anyone else seen anything like this or have any ideas on how I might resolve this issue?

Why not asking in tabbed-card repo? There are already some registered similar issues and also a new fixed version was released recently.

I didn’t ask on the Tabbed Card repo because I figured there’s more users that would see this here than there. Also, I didn’t find bug reports on the repo that suggested others had seen this problem. But you say there are some similar issues noted there. Perhaps you could link to them because I don’t see it. And yes, I should have noted, I am running the latest version.

I cannot provide a link to a particular issue, not convenient with a mobile.
In 2025.5 a particular web control was removed from HA - and this control was used in the tabbed+card. This caused “issues”, there are registered tickets in GitHub, and now a new version (have not tested it yet myself) is available.
If you suspect that something was broken in 2025.5 and still not fixed - suggest to double check that you are using the latest version, purge a browser / Frontend cache; if the issue still exist - check with a simplified card (without any other custom cards, with a default theme); then register a new ticket if there are no already present similar tickets.
