Deprecations and removals in Chrome 75
Remove overflow: -webkit-paged-x and overflow: -webkit-paged-y
These are old webkit-specific properties that allowed developers to fragment content over columns inside a scrollable region. They are now removed.
Practically speaking these aren't used. Most developers use them accidentally,
and typically when they are they force a new formatting context similar to
setting overflow: hidden.
