Gantt - Task removal not tracked in changes for filtered children

Hey,

We've hit a problem with deletion of child tasks in Gantt. When child tasks are filtered out and then removed via parent deletion, they aren't appearing in project.changes.tasks.removed. This is reproducible in the https://bryntum.com/products/gantt/examples/fieldfilters/ example by doing the following:

Change % Filter to 50, reducing the visible children in "Website Design" from 4 to 1.
Right click and delete the "Website Design".
In the JS console, run gantt.project.changes.tasks.removed

The removed array has the 2 visible tasks but not the 3 filtered tasks.

Removing the filter will not show any of the deleted tasks, and the changes still only have 2 registered as removed.

Is this intended behavior? How should we collate removed tasks when saving?
