Inline adding assignee is still inheriting all of them from parent task

I often run into issue that if there is parent task with more assignees, it gets some subtasks that are limited to less amount of people. Sadly, when adding new subtasks inline with assignees, it still copies all of them:

Adding it ends up with all 9 people being assigned, even while I wanted to assign myself only.

It is fine feature if you add task without @ assignee shortcut, but should be disabled if @ assignee is found.
