[BackLite] Brightness not sticking on app load

### The bug

While using the app `BackLite` it's supposed to not turn on the backlight if you press the button to unlock the watch - a long press is needed to turn the backlight on. However, the brightness that is correctly set upon unlock changes to maximum brightness as soon as `load(...)` is called. I've tried to mitigate this issue in several different ways, all of which have failed, and I have concluded that it might be related to the firmware, as I can't see anything else that conflicts with it. Sometimes it works right, and after installing another app, it doesn't anymore. @gfwilliams any idea if this is firmware-related?
