Also reproducible with testRunner_v5.js.

[dwrobel]

Retested on 46e2073 and it's still reproducible.

[conniefry]

Is this still reproducible with the latest master or can it be closed?

[dwrobel]

Last time when I checked it I was always blocked by #1065, so #1065 becomes prerequisite for verifying this one.

[dwrobel]

Not reproducible.
