Bug 1553227 - Remove old CSS scroll snap implementation. r=hiro
This will save us some time from figuring out what's the best thing to do in bug 1552587, so that other patches I have in flight (mainly bug 1552708) can land, since we cannot add a single byte to nsStyleDisplay right now otherwise. The code removed here is well isolated and not that complicated, so it seems to me that should be easy to bring back should we have an emergency (and I commit to doing that while preserving the nsStyleDisplay size limit if we need to :)).
