BubbleCard Pop-Up with multiple views

Hey,
Im trying to use PopUp BubleCard in two different views.

The View Button contains the Button with the link to the PopUp in the view Bubble.
This is not working. After clicking the Button it seems that theres a kind of overlay and disappears after 5 seconds (like the configuration in the pop-ip card)
The view Bubble2 contains the button and the popup and it works like expected.

Do I need to add all popup cards in the main view or is there something wrong in my configuration?

views:
  - title: Bubble
    path: bubble
    badges: []
    cards:
      - type: vertical-stack
        cards:
          - type: custom:bubble-card
            card_type: pop-up
            hash: '#2views'
            name: Kalender
            icon: mdi:calendar
            auto_close: 5000
            is_sidebar_hidden: false
            hide_backdrop: false
  - title: Button
    path: button
    cards:
      - show_name: true
        show_icon: true
        type: button
        tap_action:
          action: navigate
          navigation_path: '#2views'
        name: Button
  - title: Bubble2
    path: bubble2
    badges: []
    cards:
      - type: vertical-stack
        cards:
          - type: custom:bubble-card
            card_type: pop-up
            hash: '#1view'
            name: Kalender
            icon: mdi:calendar
            auto_close: 5000
            is_sidebar_hidden: false
            hide_backdrop: false
      - show_name: true
        show_icon: true
        type: button
        tap_action:
          action: navigate
          navigation_path: '#1view'
        name: Button

popup

Thanks!

@e0909 Did you ever figure this out? I have been wanting this as well for a long time. My mobile dashboard has over 2K lines of YAML now which makes using the UI for editing impossible.

I just found this from the author of the card: ⚪ Bubble Card - A minimalist card collection for Home Assistant with a nice pop-up touch - #55 by Cloos
