Possible duplicate of bug 1873022 and bug 1871015.

I think these all have the same underlying cause but with a couple of different visible behaviors

1. Fenix sometimes does not obey system dark/light theme
2. Fenix dark/light theme is sometimes not internally consistent (status bar, toolbar & web content have different themes at the same time)
3. Fenix status bar & Settings menu text/background sometimes incorrectly themed (eg dark text on dark background or light text on light background)
