Improve scrolling on sliders
Currently, when you scroll through a view, you can easily accidentally change sliders and combo boxes. When your cursor hovers e.g. a slider, it does not scroll the view any more but rather it changes the slider. A great example of this is the audio panel in GNOME Settings:
Example in GNOME Settings (I want to simply scroll up/down but I keep changing settings without intent)
To improve this, it should work like this:
- If you start scrolling on the slider, it should change the slider
- If you start scrolling on the view, it should scroll the view
- When you started scrolling on the view, but during this you hover the slider you should still scroll the view
