   7      This test is a variant of flexbox-dyn-insertAroundText-3.xhtml with the
   8      inserted spans being empty & having padding. This triggered invalidation
   9      issues with an older work-in-progress patch, so I'm adding this reftest to
  10      track that issue & prevent it from regressing.
