Maybe "precedes"?

this->precedes(that)

seems unambiguous, but

this->isPreceding(that)

is awkward...

Let me take precedes() here.

 {
-    TreeNode<HTMLImport>::appendChild(child);
+    for (HTMLImport* i = this; i; i = traverseNext(i)) {
+        if (i == import)
+            return true;
+    }
+
+    return false;
+}
+
+void HTMLImport::appendImport(HTMLImport* child)
+{
+    appendChild(child);
 
     // This prevents HTML parser from going beyond the
     // blockage line before the precise state is computed by recalcState().
