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

* Tech Preview, Release 71 (Safari 12.1, WebKit 14607.1.15)

The attached script works in Chrome. It fails in Safari with InvalidStateError: "The object is in an invalid state".

The script just gets RtpSender parameters via getParameters(), set active=false into the only encoding and applies the modified parameters via setParameters().
