Comment 3

[Andrew McCreight [:mccr8]]

These leaks are all in fetch/metadata/redirect/ WPT. There are already a ton of leaks whitelisted in that directory, so presumably this particular failure is just a sign of some leaks that should be whitelisted, but of course it would be nice to actually fix these leaks.

Let's just paper this over. I can't imagine anybody is going to get around to this intermittent leak any time soon.
