Specification
https://drafts.csswg.org/css-ruby/#ruby-overhang


Summary
Support of new CSS property `ruby-overhang` is added. The property accepts one 
of `auto` and `none` keywords, and controls overhang of ruby annotation text.


Blink component
Blink>Layout>Ruby


Web Feature ID
ruby-overhang


Motivation
A ruby annotation can sometimes obscure adjacent content when it overhangs. The 
ruby-overhang property gives authors a way to disable this behavior and prevent 
unwanted overlap.


Initial public proposal

TAG review

Goals for experimentation

Open questions about a feature may be a source of future web compat or interop 
issues. Please list open issues (eg links to known github issues in the project 
for the feature specification) whose resolution may introduce web 
compat/interop risk (eg, changing to naming or structure of the API in a 
non-backward-compatible way).
