Using VE on Commons. I have now twice typed a detailed bug report using VE's own "Help -> Leave feedback about this software", and upon clicking submit get the helpful error message "Error: Unable to post to given feedback title" and lost the entire report. In case of error, the report should be echoed back in the Error dialog box so that at least it can be copied/pasted. The Subject field contained no special characters and wasn't overly long.
Secondly, the Submit Feedback dialog links to "VisualEditor/Feedback" on Commons (ie. https://commons.wikimedia.org/wiki/VisualEditor/Feedback - a page which doesn't exist) rather than here.
