Style chrome scrollbar

It's usually recommended to not mess with the browser's scrollbar CSS but horizontal width is too precious, it's probably worth breaking that convention (twitch does it anyway)

Enabling chrome://flags/#overlay-scrollbars does the trick for now, apparently they are working on "Fluent overlay" currently that is better for the CPU/GPU and is already used in Windows 11.
