overflow-inline/block
Description
The overflow-inline and overflow-block CSS properties, which are the logical equivalents of overflow-x and overflow-y, are currently only supported in Firefox. When writing an entire page layout with logical properties, the overflow-* properties have long been a weird edge case where the logical versions just aren't supported in browsers.
Note that this might be less important than other interop things, but I think implementation should be rather easy and straightforward on the browser's side, so hopefully it doesn't deprioritize other features too much.
