With new iOS 13.2.2 https://bugs.webkit.org/show_bug.cgi?id=202405 seems fixed.

But I found older and new bugs related to the audio/video muted track state.

UA: Mozilla/5.0 (iPhone; CPU iPhone OS 13_2_2 like Mac OS X) AppleWebKit/605.1.15 (KHTML, like Gecko) Version/13.0.3 Mobile/15E148 Safari/604.1

In safari iOS, you have a red icon in the upper left side of the navbar that display a microphone in case of audio only GUM, and a webcam in case of video only or audio+video GUM.

This is almost fine, but there are 2 scenarios:

GETUSERMEDIA audio only:

in the nav bar a red microphone appears and everything's ok.
if I click the microphone, it turns into a webcam red icon with the "muted" bar. the receiver will stop to receive audio.
if I click again nothing happens.
if I set safari in baground and then reopen it, the red muted webcam disappear and return a microphone with a red line.
anyway, there's NO WAY to "unmute" audio.

GETUSERMEDIA audio + video:

in the nav bar appears the webcam red icon.
if I click this icon, a red line appears signaling that is "muted".
the receiver stop to receive both audio and video.
if i try to click on the webcam in the muted state to unmute, nothing happens.
Interestingly, if I put safari in background and back in foreground, the video reappears, and the counterpart receives it but the audio never recovers.

in any case, the mediastreamtrack, when pressing the red icon goes to muted state, but there's no way to recover the audio one.
to recover video, you have to do the safari background/foreground trick.

This is a mess
