Problem

Up until recently, ticket editing interface (/ticket/75/edit/) allowed users to pick dates easily with a datepicker. See Phabricator for screenshot.  

Outcome

Investigate why datepicker doesn't appear anymore. For this task to be considered completed, you don't have to find out the root case, you must, however, make geniune effort to investigate. Document what you did, in the case you won't success, the documentation will be important for further developers.   If you manage to fix the error, 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.
