  Result: FAILED

The cause looks like it is because of "The command failed because the referenced element is no longer attached to the DOM". We have seen this happen sometimes in the past with various tests. I suspect that the problem does not happen often.

Maybe #6227 is related, but maybe not.

Investigate if this "details panel" step can be made more reliable.

[phil-davis]

should have been fixed by #6499

If the scenario fails again, then please reopen the issue.
