In step 2, are you referring the the top-level "Project" in the left-hand navigation tree? I cannot reproduce the issue using that item or any other.

@Gary, I tried clicking on "Project" header multiple times and got the error message. see attachment.

[Gary W. Smith (gary-w-smith)]

Got it. Now I see it too.

    Navigation causes undefined error when clicked on twice

    Using the jquery find function on a regular element causes this error. To
    resolve this issue, we have to wrap it as a jquery element.
