bubble-card pop-up v3.2.x not working when wrapped in decluttering-card

[e2ret]

Bug description

After bubble-card updated to v3.2.0, pop-ups wrapped in decluttering-card templates stop working correctly:

• Pop-up shows "You need to define a unique hash" onboarding message despite hash being defined
• Pop-ups reserve empty space in dashboard layout when closed

Root cause

bubble-card v3.2.x uses e.getRootNode() to find parent context. When wrapped in decluttering-card, getRootNode() returns the shadow root of decluttering-card instead of the view root, so bubble-card cannot find its hui-card wrapper and cannot read the hash.

YAML

korridor_bubble_popup:
  card:
    type: custom:bubble-card
    card_type: pop-up
    hash: "#korridor"
    cards: []

# In dashboard:
- type: custom:decluttering-card
  template: korridor_bubble_popup

Expected behavior

Pop-up works normally with hash defined in template.

Actual behavior

bubble-card ignores hash, shows onboarding, reserves space in layout.
