Voice recording UI shows that voice is being recorded when in fact it doesn't

Description

When starting recording a voice message, an input device has to be initialized before being able to record anything -- it takes time. But at the same time voice recording UI appears and it looks like we're recording something when in fact we don't. This is wrong because it may lead to irritating cut-ins (typically 1 second or less, but may be more with external devices) in voice recordings.

Expected Behavior

UI clearly shows that the audio input device is not ready to record voice memo e.g. red bulb doesn't blink at all.

Actual Behavior

UI behaves like something's recording, even though the recording timer doesn't start -- which is actually correct

Steps to Reproduce

1. Start recording a voice message and instantly say or do some noise
2. Check that aforementioned noise is absent from resulting recording but you thought it should have been recorded.

It's more obvious when you connect to e.g. a Bluetooth audio device which has voice input capabilities -- there may be really long delays before you can actually start saying something -- but this also happens while using an internal mic.

Screenshots and Videos

Environment

Device: iPhone 11

iOS version: 13.6.1

App version: 7.0.1

Start by reproducing voice-message recording on an iPhone, especially with a Bluetooth audio device, and inspect the voice recording UI while the input device initializes. Done means the recording indicator does not imply active recording before the timer starts, and audio captured during that delay is not presented as recorded.
