Description

@TalbotG recently asked about this test from @upsuper http://wpt.live/css/css-ruby/abs-in-ruby-base-container.html which... I'm not really sure what it's trying to assert.

I don't think our spec is clear what happens when various ruby boxes are relpos'ed, do they form containing blocks for abspos descendants or no, and we should figure out what we should be doing and clarify it.

Research direction

Start with the referenced WPT test at css/css-ruby/abs-in-ruby-base-container.html and determine what assertion it is intended to make. Read the CSS Ruby specification around relatively positioned ruby boxes and absolutely positioned descendants. Done means the containing-block behavior is resolved and the specification is clarified accordingly.
