[Chris Peterson [:cpeterson]]

Clearing the Fission Milestone flag. This WR OOM signature spiked on Windows 7 in Beta 94, but Fission's Windows 7 crashiness has been a problem since much earlier than that.

Copying crash signatures from duplicate bugs.

Comment 4

[Jeff Muizelaar [:jrmuizel]]

Downgrading to S3 because this isn't particularly actionable. Maybe we'll make it better when we change how we do display lists with WebRender

Comment 5

[BugBot [:suhaib / :marco/ :calixte]]

Closing because no crashes reported for 12 weeks.
