Map card: may show a minimal zoom when placed inside auto-entities

[ildar170975]

Consider the code:

type: vertical-stack
cards:
  - type: custom:auto-entities
    card:
      type: map
      auto_fit: true
      fit_zones: true
    entities:
      - zone.home
    filter:
      include:
        - entity_id: person.ildar

Use-case: show device_tracker or person entities AND some zone. Here I chose one particular person entity & home zone.

Select a dashboard in STORAGE mode, add a new card with this code. How it is displayed:

Zoom is minimal. Pressing F5 does not help.

Save the dashboard (exit "edit mode") - still zoom is minimal: Pressing F5 does not help.

Go back to "edit mode" - the card is shown normal (zoom is OK). Press F5 - again zoom is minimal.

In these cases I do not observe the issue:

1. The card is shown in Editor.
2. Same card is placed on a dashboard in YAML mode.
3. No vertical-stack is used:

   type: custom:auto-entities
   card:
     type: map
     auto_fit: true
     fit_zones: true
   entities:
     - zone.home
   filter:
     include:
       - entity_id: person.ildar

4. auto-entities is not used:

   type: vertical-stack
   cards:
   - type: map
   auto_fit: true
   fit_zones: true
   entities:
     - zone.home
     - person.ildar

5. Those auto_fit & fit_zones options have different values or omitted (i.e. using default false values).
