Theme settings not saved when watching a video in the app

Hi,

I'm using the dark mode of BlueSky (and Sky) but when I watch a video on YouTube in the app it goes into the light mode and does not remember my settings or check my system settings.

This might be merged with #29.

Does this behave differently in https://github.com/jcsalterego/Sky.app/releases/tag/0.4.2 ?

It does! Only the top is left now.
