GtkScale does not remove its "dragging" CSS class after right click
When you press and hold a mouse button on a GtkScale
it will enter the "fine-tune" mode (scale trough highlight will get wider). This happens because the "dragging" CSS class is added to the scale, but when during holding the left mouse button user clicks with right button, the CSS class will not get removed and scale will be left in its "dragging" state with wide highlight.
This can be easily reproduced on any GtkScale
(for e.g. video position in GtkVideo
).
Linux, GTK4 latest git at the time of writing (db456a70), gnome-shell, Wayland session.
