@jcfranco this fixes the issue. However, I noticed other sort-handle events are being stopped rather than being cancelled so this is inconsistent.

However, I noticed other sort-handle events are being stopped rather than being cancelled so this is inconsistent.

The example from the description is fine since its handling internal events.

If you mean how other public handle events are non-cancellable, we have to flesh out our cancelable event story first. We've been mostly making events cancelable as needed.

Code changes LGTM! Can you add a test before merging?

Side note: we should add a doc snippet for cancelable events. cc @geospatialem @DitwanP
