is a flakey text failure on BigSur in wk2 on Apple Silicon Macs only.
PASS: responseSource should be Symbol(network).
PASS: estimatedTotalTransferSize should be >= (encoded body size + headers).
PASS: networkTotalTransferSize should be >= (encoded body size + headers).
PASS: requestHeadersTransferSize should be non-empty.
I cannot reproduce this failure, as it only occurs on Apple Silicon Macs, and I do not have access to one of those systems.
The history indicates that the test has been flaky failing fairly close to when it started running on Apple Silicon Macs.
As such, I have updated the expectations to flaky (Pass Failure) specifically for BigSur wk2 Apple Silicon Macs here:
