     // in the case where further processing on the node is required. Returning the shadow ancestor prevents a
     // regression in touchadjustment/html-label.html. Some refinement is required to testing/internals to
     // handle targetNode being a shadow DOM node.

     // instead have dedicated test methods so we only do this work in tests.
