Details

We compute various abspos constraints in ReflowInput [1], and after AbsoluteContainingBlock reflows the frame [2].

The question is: do we need compute them for abspos continuations? Can those values carry over from the first-in-flow?

Summary: Investigate if we can skip computing offsets, margins, etc. for abspos continuations → Skip computing offsets, margins, etc. for abspos continuations
