It seems that the same font, "Cascadia Code", is displayed in the both themes. A difference bettwen the themes is font style: Molokai theme uses the italic style (inherited from Monokai theme) as opposed to the normal style in the default dark theme.

The shape of Cascadia Code greatly differs between the normal style and the italic style, so at first glance they look like different fonts :)
