Google Code-in

Tracker is a financial tracking app used primarily by Wikimedia Czech Republic. When you try to add an ack from the user interface (for instance, you open a ticket you created and hit "presubmitted"), you won't be allowed to fill a comment - which was the case previously.

Your task is to investigate the error and fix it. You are expected to send a patch for wikimedia-cz/tracker repository, hosted at Wikimedia Gerrit. When claiming task on GCI website, student should claim a respective Phabricator task as well.
