Experiments with scroll customization in Chrome.
A limited version of the API (for touch scroll gestures on main thread scrolling) has landed in Chrome behind a runtime flag. To use it on a desktop Chrome you need to emulate touch in devtools and pass the following flags:
--disable-threaded-scrolling --enable-blink-features=ScrollCustomization
Documentation is here.
Latest version requires a custom build that includes this Chrome patch in progress.
