Moving scrollbar does not trigger scrolled callback (maybe a bug)

[thooore]

Hi!
I'm new to slint and trying to figure stuff out. Right now I'm trying to create a scrollable area with a header that acts as a timeline, where the header scrolls with the content. When I test the component locally the scrolled callback only triggers on mousewheel scrolls, and not if I click and move the bottom or right scrollbars. I think this is a bug since it seems to trigger when I run it in slintpad. I think I can create a workaround using a TouchArea if the bug just appears for me, but it would be great if someone knows a less hacky solution.

I'm running this stack on manjaro if it helps:
Display: wayland server: X.org v: 1.21.1.18 with: Xwayland v: 24.1.8
compositor: gnome-shell v: 48.4 driver: X: loaded: amdgpu
unloaded: modesetting,radeon alternate: fbdev,vesa dri: radeonsi
gpu: amdgpu display-ID: 0

Thanks!

I tried it and yeah, this seems like a bug. The callback is specifically for user interaction, but at least for the Qt backend it never emits it for scrollbar drags.
