Provide better solution for long parent subject on issue list per #13673
The change done to #13673 broke a lot for us... and would like that to be reverted.
Seeing only parent issue number makes the column useless because we do not know what the parent is about :/ often parent subject contains general information (e.g. test A) and then more details in subtasks (e.g. prepare setup, make report, etc.), now I see only few tasks like prepare setup with no information what the setup is for :/
