Re: [csswg-drafts] [css-view-transitions-1] Clarify implications of scrolling during a transition (#10197)

https://codesandbox.io/p/sandbox/m7zyzc _(forked from a demo by @joshwcomeau)_ nicely demonstrates the problem with the current specced approach.

With the long `animation-duration` used in the demo, the problem becomes very much visible: because the target scroll position gets updated in the target value of the subject, scrolling doesn’t happen immediately but is controlled by the `animation-duration`.

https://codesandbox.io/p/sandbox/xldyq8 is the adjusted version of that demo, that uses the approach as described above: it updates the position of the `::view-transition` on scroll. The result is that it correctly responds to scroll.
