The following layout test is failing on Mac WK2

http/wpt/webauthn/public-key-credential-get-success-hid.https.html

Probable cause:

Unsure of regression point. Has been a flaky failure as far back as the history of the dashboard goes. Searching through trac history this test and http/wpt/webauthn/public-key-credential-create-success-hid.https.html have a history of being flaky failures and several fixes have come out and test remains flaky. 

Both tests were added in https://trac.webkit.org/changeset/238166/webkit
