The `#[bg=default]` does not work properly(?)

[Dolfost]

I am trying to set the @catppuccin_battery_text to "#{battery_color_charge_fg}#{battery_percentage}" Result is: (notice the background of 100%)

So, to make it the default one I do

set -g @catppuccin_battery_text "#{battery_color_charge_fg}#[bg=default]#{battery_percentage}"

But I get the same result. How to get the status line background color?
