The problem

Describe precisely the problem you're facing and add screenshots to illustrate

"Do not Disturb" mode sometimes turns off on its own, even though no schedules are set and 'Duration for Quick Settings' is set to 'Until you turn it off'. This happens when "Do not Disturb" mode is enabled via any way (e.g. Quick Settings or "Moments" slider).

I have not tested if the bug still happens when the slider is configured to do something different than setting Do Not Disturb, but I will test this starting today.

Steps to reproduce

• Enable "Do Not Disturb"
• Wait around 24 hours (sometimes happens earlier)
• At some point a toast will appear with "Do Not Disturb disabled" as if the user changed the slider. Usually while the phone is being used for an irrelevant task (e.g. watching videos, browsinf the web)

Paste any relevant logs (adb logcat) in the codeblock below if you have any

(no logs from the event yet, as it is too unpredictable when it happens. I will try to capture logs when it next happens)
