Just performed these steps and here are the results.
Steps 1-2-3: was able to see comment box and my comment as it should show up.
Steps 4-5-6-7-8: was NOT able to see my text as I was typing. Even tried logging out and log back in to see if that would fix things but I couldn't even log out. After several attempts it gave me an error message. I force closed and restarted only to find i was logged out. So logged back in and tried but still could not see comment box as I was typing my comment. Have repeated recently and it's hit or miss right now.
