[Bug]: Pull to refresh works with touchscreen mobile device but does not work in desktop app with touchpad

[CaptainMorgan12]

Describe the bug

Should be standardized. Using a single finger in timeline on touchscreen it pulls to refresh with animation. However using two fingers on touchpad on desktop device it does not. See feature implementation #283

Steps To Reproduce

1. on desktop with touchpad scroll to timeline top
2. swipe two fingers down
3. observe no pull to refresh animation or reload occurs

This would be tricky to fix. Possibly impossible - GtkScrolledWindow really doesn't cooperate well with other gestures, same as how back swipes are broken. Even in GTK3 where those worked they only worked when there's no horizontal scrolling, and here it's vertical scrolling + vertical pull to refresh swipe.

FWIW, you can still trigger it with a touchpad by dragging it from the top

As for the ScrolledWindow,the initial implementation (ab)used the overshot, not sure if it's worth adding it again since dragging works just fine:

Yeah, I wouldn't. Note that it's also pretty broken on touchscreen atm.

true drag and pull works, thanks for pointing that out! for consistency though would it be better to try to align touch on touch screen device interaction and touchpad on desktop app interactions, if possible (also maybe once you reach the beginning of timeline maybe having some small text on top that says "Drag/Pull to Refresh" would be a good que?
