Double click on list issue (in task view) should expand to card (or summary) form

Old feature of issues in task view (and planning view, byt the way) was a double-click meant that issue alone expanded to be in summary (or card) form. This allowed updaets to fields in those forms directly on the task or planning view.

Now it seems that task view and planning view in list form doesn't allow this direct method of update or examination.

Please re-instate this feature. It was a useful 'marker method' for group discussion in planning.
