MDSelectionList properties cannot be modified

I am using an MDSelectionList inside a tab with an MDNavigationRail to switch between screens, however, when I try to customize the MDSelectionList, none of the visual changes apply. I thought that maybe it is a problem with the widget itself but then I separated it and the property changes worked. How can I make the changes apply to the selection list? (I am using kivymd 0.104.2.dev0 from the master branch) My Code:

from kivy.config import Config

Config.set('graphics', 'width', '850')
Config.set('graphics', 'height', '530')
Config.set('graphics', 'minimum_width', '850')
Config.set('graphics', 'minimum_height', '530')
from kivy.lang import Builder
from kivymd.uix.card import MDCard
from kivymd.uix.tab import MDTabsBase
from kivymd.app import MDApp


class SettingsTab(MDCard, MDTabsBase):
    pass

class Example(MDApp):

        super(Example, self).__init__(**kwargs)
