`on_scroll` is not fired when scrolling via operations

Is there an existing issue for this?

Is this issue related to iced?

What happened?

When scrolling via scroll_to or snap_to, the callback passed through on_scroll is not fired, hiding thus vital information about the current offset of the scrollable that can't be queried through other means.

If I show a percentage indicator of some scrollable in my app and perform a scroll_to operation, I don't know what's the new relative offset.

What is the expected behavior?

on_scroll should fire on every scrolling event.
