The order of the api diff notations is inconsistent between the output for` --compare-doc-comments` and the diff boxes.

"① Only in: Valhalla; not in: Master."
vs.
in the box header:
"Not in Master; only in Valhalla"

Command line like:
`apidiff \
    --api Master \
      --jdk-build $REPO0/build/macosx-x64 \
      --system $REPO0/build/macosx-x64/images/jdk \
      --api-directory $REPO0/build/macosx-x64/images/docs \
    --api Valhalla \
      --system $REPO/build/macosx-x64/images/jdk \
      --jdk-build $REPO/build/macosx-x64 \
      --api-directory $REPO/build/macosx-x64/images/docs \
    --compare-doc-comments yes \
    --include java.base/ \
    --output-directory $OUT
