The PHP code should never see a `<span class="mw-headline">` node
since MediaWiki change If04d72f427ec3c3730e757cbb3ade8840c09f7d3,
but we have to support it for our old integration tests (T363031).
Improve code comments to explain this and move the handling to
one place, so that it can be deleted more easily in the future.
Follow-up to 08f61b2609.
