To make an element scrollable in CSS, currently the following has to be done: ``` .scrollable { overflow-y: auto; -webkit-overflow-scrolling: touch; } ``` The WebKit-only `-webkit-overflow-scrolling: touch` adds momentum scrolling. However, the scroll inertia is drastically different from the native scroll on `<html>` element. Since it's a WebKit-specific issue, could you please add another CSS property to use the native-like inertia for bigger scrollable elements?

Resolved via https://trac.webkit.org/changeset/211197/webkit, which makes WKWebView have the same scroll deceleration as -webkit-overflow-scrolling: touch

Thanks a lot for fixing this! One thing I wanted to confirm. From the fix description it sounds like the scroll inertia in the WKWebView will now be the same as for an element with `-webkit-overflow-scrolling: touch`, right? Does this mean that Safari will eventually have the same scroll inertia as well?
