  Log Message:
  -----------
  RenderObject::markContainingBlocksForLayout should check for non-positioned RenderLineBreaks too (and not just for RenderText)

Reviewed by Antti Koivisto.

Do not use the computed value for out-of-flow position as some of the renderers may override it (e.g. RenderLineBreak). Using incorrect containing blocks while dirtying the ancestor chain puts the render tree to an unexpected state.
