[iOS] audio level switches to VC level when starting microphone capture even if audioSession type is set to 'play-and-record'

Repro steps:
1. Close Safari, set audio level to 50%
2. Load https://jsfiddle.net/63x57vnb/, click 'start microphone', grant microphone access and set audio level to 100%
3. Restart Safari and load https://jsfiddle.net/63x57vnb/
4. Audio level is at 50% (even though navigator.audioSession.type is set to 'play-and-record'
5. Click 'play bunny', video should start playing
6. Verify audio level is still at 50%
7. Click on 'start microphone', grant microphone access
8. Verify audio level is now at 100%.

I would have expected audio level at step 4 (or maybe 6 since webkit might not have activated the audio session) to be at 100%
