Script that reproduces the issue. Just run it in Safari 12.1 console with "Unified-Plan" enabled.

Scenario:

* Have a pc with an audio transceiver for just sending audio (it does not receive audio from the remote), so it has `direction: "sendonly"`.

* Call `transceiver.sender.replaceTrack(null)` and `transceiver.direction = "inactive"` and do a new SDP O/A.

* No matter where `transceiver.direction = "inactive"` is set. The `transceiver.direction` remains "sendonly" and its m=audio section also remains with "a=sendonly".

This works as expected in Chrome and Firefox.

Script attached.
