Comment 8 for bug 953757

Could we please get a feature freeze exception for this in gtk3?

This would unify slider behavior again and we could get rid of the ugly "act-as-if-middle-button-was-pressed" hacks in IDO and gnome-control-center.

I've submitted the patch upstream at https://bugzilla.gnome.org/show_bug.cgi?id=563688. GNOME designers support the change, so it has good chances of being accepted.

The package with my patch builds and works as expected. I've been running it for a bit on my system and tested every slider I could find, in particular all default applications.
