Not respective system theme setting causes wrong colors on MIUI 12
Our default theme is the light theme. The expected new behavior is to default to the system theme setting, so all apps look the same.
MIUI 12 running Android 11 is forcing apps to use a dark theme somehow causing Briar to use a fake dark theme while set to the light theme which looks bad and gets colors wrong. Navigating to settings => Display and changing theme to system default fixes this.
