For following case, drag scroll thumb (the green block) can scroll as normal.
But if you click the wheel(middle) button, the whole page is blocked, even after reload or switch page.


```html
<!DOCTYPE html>
<html lang="en">
<head>
    <style>
        main {
            overflow: auto;
            scrollbar-gutter: stable;
        }

        div {
            background: linear-gradient(90deg, blue, red);
            width: 4000px;
            height: 100px;
        }

        main::-webkit-scrollbar {
            width: 16px;
            background-color: black;
        }

        main::-webkit-scrollbar-thumb {
            background: green;
        }
    </style>
