Lost of user-friendliness in the Tasks app

The Tasks app, with 18.3, brought a few novelties. One was supposed to be an enhancement to the tool, but instead of enhancing, it has created problems.

Previously, no matter where we dropped the task it would be associated to the same activity.  To change we would need to open the task dialog box. Now, we can change to which activity the task belongs by simply dragging it in the hopper or by dropping it in the weekly board on the desired activities.

However, if there are already tasks in the weekly plan and we wish to drop another task, from a different activity, then the only way we have to drop the task allocated to the proper activity is to drop on top of the date as in the figure below.
