Why don't calls to emergency numbers show in the Phone app's call log? I recently had to make an emergency call.

I later noticed in my device's call logs in the Phone app that the emergency number I called doesn't show up in the call log. (In other words, no entry shows of the call; no trace in the call log that I called an emergency number.)

Why is this? Is this intentional and by design, or is it a bug?

(Using stock Android 8.1 with latest updates on Nexus 6P.)
Logically they should for traceability of crank / genuine distress emergency calls. As a matter of fact   Call  |  Android Developers specifies extra time accuracy for emergency calls:


  Extra key used to indicate the time (in milliseconds since midnight, January 1, 1970 UTC) when the last outgoing emergency call was made. This is used to identify potential emergency callbacks


(Emphasis supplied)

Try changing the call app and if it still persists report to OEM / ROM developers
