Description John Wilander 2020-01-09 14:12:06 PST 
Since m_sessionID is optional, we need to check that it exists before asking it whether the session is ephemeral.

I'm not 100% sure this is the cause, but we have a flakey regression in a resource load statistics test, and this seems like a plausible candidate:

Comment 7 Jonathan Bedard 2020-01-10 13:47:23 PST 
Although <https://trac.webkit.org/changeset/254296> is also a plausible candidate.
Comment 8 John Wilander 2020-01-10 15:08:42 PST 
Thanks for flagging, Jonathan! I'm trying to address the flakiness in https://bugs.webkit.org/show_bug.cgi?id=206100.
Comment 9 John Wilander 2020-01-14 10:49:19 PST 
The flaky test looks all green after my latest change.
Comment 10 Jonathan Bedard 2020-01-14 11:22:49 PST 
Looks good so far...still need a few more test runs to be confident.
Comment 11 Jonathan Bedard 2020-01-16 15:02:01 PST 
I think we can pretty confidently say things are fixed now.
