Need documentation for how to anonymously(safely) file a bug in trac.torproject.org

I never seen some documentation or tutorial say how to anonymously(safely) file a tor bug in trac.torproject.org. For example: Is public contents of "Copy Tor Log To Clipboard" in trac.torproject.org can cause anonymity risk? How can I avoid such risk when I report bug in trac.torproject.org?
