Looks like the test has been flakey flailing close to when it started running on BigSur, with the first failure at r272143. I was able to reproduce the failure at BigSur Debug ToT using the following test:

run-webkit-tests webrtc/libwebrtc/release-while-creating-offer.html --debug --iterations 1000 -f

Updated test expectations to Pass Failure here, while test is under review:
