- Double-click to edit the start date of the first task "Project Initiation". This is a top-level task with 3 child tasks.
- Change its value from 02/04/2019, to 03/04/2019.
- Instead, the value gets set to 04/04/2019.
- Change the value again, this time try set it to 01/04/2019.
- Instead, the value gets set to 29/03/2019.
Refresh the page to start over, and instead try the same on the second task "Identify Site location", which is a child task of "Project Initiation". In this case, there are no problems with the value being set according to input.
Selecting the date in the calendar popup, or manually typing it in, seems to make no difference.
