Re: [csswg-drafts] [css-overflow] add method to prevent elements from contributing to scrollable overflow (#8361)

> Regarding scrolling operations, it would be useful to be able to ignore the sticky offsets of an element. That way, scroll operations would scroll to the in-flow position of a sticky element.

Yeah we tried to do this earlier by default (see #1459), however it turned out to have many cases where it wasn't reasonable behavior so perhaps having it as a controllable behavior would allow authors to select it when it made sense.

I agree, sticky position is something that wouldn't make sense to ignore for overflow contribution but is very useful for scroll alignment.

In order to avoid making the property sound like it is doing the same thing as `scroll-snap-align` ([which can be used for scroll alignment without snapping](https://drafts.csswg.org/css-scroll-snap-1/#:~:text=snap%20container.-,The%20user%20agent%20may%20also%20do%20this%20even%20when%20the%20scroll%20container%20has%20scroll%2Dsnap%2Dtype%3A%20none.,-If%20a%20scroll)), it would probably be good to give it a name like `scroll-align-origin` or `scroll-align-box`.

TLDR, I propose two new properties:
```
scroll-align-origin: normal | ignore-transform || ignore-sticky-offset;
overflow-contribution: normal | none;
```
