Issue Summary

When moving a sub-task to Done in a kanban board, the "Update Parent Issue" pop-up is displayed even if there are sub-tasks opened for the mentioned parent issue, as long as they are not returned by the board filter.

Steps to Reproduce

1. In a Kanban project, create a parent issue (Task, Story or Bug)
2. Under that issue, create two sub-tasks
3. Add the component "test" to one of the sub-tasks
4. Edit your board filter to "Project = xyz and component = test", so only one of the sub-tasks above will be displayed
5. Navigate to the Kanban board and move the sub-task to "Done", by dragging and dropping it in the rightmost board column

Expected Results

As there are still open issues under the parent, the "Update Parent Issue" pop-up should not appear.

Actual Results

the "Update Parent Issue" pop-up is displayed.

Workaround

Edit the board filter to display all the sub-tasks under the parent.
