No selection-mode toolbar style in gtk4 Adwaita
This is almost certainly the wrong place. Please point me at the right one, thanks.
In the GNOME HIG, a special toolbar style for "selection mode" is recommended. At least implicitly by the mockup. And in practice, apps implement that by setting the
selection-mode css class to their GtkHeaderBars.
But in gtk4, support for that css class was removed from Adwaita.
- Going forward, is it still GNOME Design's recommendation to have a special style there?
- If not, I think we should update the HIG mockup.
- Otherwise, I'd vote for finding a new place for this styling to live, to avoid doing it manually in a bunch of apps. Maybe in the theoretical libhig/libadwaita/libhandy library?
