This does works on Safari on macOS, but not on Safari on iOS (the physical device, not emulated).
It (kind of) falls back gracefully, always showing the shadow on the right side whether you scrolled or not but never revealing the left shadow.

Haven't found a fix for it though, so just a little heads up for now.

Pure CSS version, with correct variables:

    --bg-color: 255, 255, 255;
    --shadow-alpha: 0.2;
    --shadow-color: 0, 0, 0;
    --shadow-height: 100%;
    --shadow-weight: 14px;

    background: linear-gradient(
        90deg,
        rgb(var(--bg-color)) 0%,
        rgba(var(--bg-color), 0)
      ),
      linear-gradient(-90deg, rgb(var(--bg-color)) 0%, rgba(var(--bg-color), 0))
        100% 0,
      linear-gradient(
        90deg,
        rgba(var(--shadow-color), var(--shadow-alpha)),
        rgba(var(--shadow-color), 0)
      ),
      linear-gradient(
          -90deg,
          rgba(var(--shadow-color), var(--shadow-alpha)),
          rgba(var(--shadow-color), 0)
        )
        100% 0;

    background-attachment: local, local, scroll, scroll;
    background-color: rgb(var(--bg-color));
    background-repeat: no-repeat;
