When is that timeout added exactly?

It feels like there is a timeout preventing scroll chaining *after* the end of the overscroll. This doesn't seem useful, as it should be possible to scroll out of the inner scroll way before that, *during* the overscroll.

If the user is overscrolling and scrolls again in the same direction, scroll chaining should take place right away. This is how it behaved before STP 117, and how it behaves in similar situations accross macOS and iOS native interfaces.

Now maybe there can be a short timeout between the start of the overscroll and the possibility to trigger scroll chaining with a new scroll gesture, but I don't think this is when the timeout is used at the moment?
