Map card configuration - light map in dashboard dark theme?

Hi community,

With a recent HA update, my light coloured map (map card in full view) changed from light to dark and I would like to get it back to light coloured card. Could anyone help me?
I noticed when my HA default dashboard theme is light, then I can have a light and a dark map card, but when my HA default dashboard theme is dark, then I only can have dark maps.

This is my card configuration:

type: map
entities:
  - entity: device_tracker.iphone_guido
hours_to_show: 240
dark_mode: false

If you disagree with the current implementation - join to the discussion in that thread.
