Lock screen interferes with ending calls

What problem did you encounter

Lock screen interferes with ending calls.

What is the actual behaviour?

When I am in a call and we have said goodbye, I'd normally hang up the call. I can't, though, because the lock screen shows up during the call. I have to enter my passcode by which time the other person on the call has already ended it. I have to reopen calls just to be sure we've disconnected.

What is the expected behaviour?

The Calls app screen should not be blocked by the lock screen so the user has access to the hang up button to end the call.

How to reproduce

Please provide steps to reproduce the issue. If it's a graphical issue please attach screenshots.

This happens with every call that lasts long enough for the lock screen to kick in (in my case, that's two minutes).
