Styling Browser Mod popups - n.forEach is not a function

My Home Assistant version: 2023.12.4

My lovelace configuration method (GUI or yaml): GUI

What I am doing: Styling popups with Browser Mod like the example at the bottom of this Page.

Works without problems in Card Mod version 3.3.1, in newer versions the error message appears.

What I expected to happen: No error

What happened instead: Console Log Error

Minimal steps to reproduce:

Create test button, press button, popup appears, when closing the error message happens in browser console.

type: button
show_name: true
show_icon: true
tap_action:
  action: fire-dom-event
  browser_mod:
    service: browser_mod.popup
    data:
      title: Teal background
      content: Where did the dashboard go?
      card_mod:
        style:
          ha-dialog$: |
            div.mdc-dialog div.mdc-dialog__scrim {
              background: rgba(0, 128, 128, 0.9);
            }

Error messages from the browser console:
