Description

When scrolling the wt website [link] with Chrome touch simulator for a while, you can see throttling message on console like this:

Throttling navigation to prevent the browser from hanging. See https://crbug.com/882238. Command line switch --disable-ipc-flooding-protection can be used to bypass the protection

On my android phone Chrome, scrolling wt website is noticeably not smooth, comparing it with other websites like qt.io.

It was touching the history API every 10 ms, but really we only need to update the scroll position once the user has stopped scrolling. I just pushed a commit that limits this update to happen only (100 ms) after the user has stopped scrolling.
