--enable-features=TouchpadOverscrollHistoryNavigation 

Official Chromium Google Chrome dropped it from chrome://flags long ago but the feature itself works in wayland when Thorium (or any chromium based browser) is launched with this flag.

Right now on every Thorium release I rename Thorium binary to something else and create a wrapper with the actual binary name that launches Thorium with this flag. While this is not a problem for me, I'd appreciate if I didn't have to.

Can you please add this back in Thorium as a flag?
