Description Martin Robinson 2021-07-07 06:20:10 PDT

https://drafts.csswg.org/css-scroll-snap-1/#scroll-snap-align says:

> Start and end alignments are resolved with respect to the writing mode
> of the snap container unless the scroll snap area is larger than the
> snapport, in which case they are resolved with respect to the writing
> mode of the box itself. 

The code should be updated to implement this part of the specification.
