+    @param selector register confirm handler for elements identified
+                    by this CSS selector. When a CSS selector contains
+                    double and single quotes, we won't add any of
+                    those around the selector automatically. Instead,
+                    the user must specify them explicity, for instance
+                    like this: ... -selector {'[name="o\'hara"]'}. If
+                    the selector does not contain any single or double
+                    quotes, we can let the user omit them, as for the
+                    case of a simple tag name selector: ... -selector
+                    "li". Quotes can also be omitted if the selector
+                    contains only one kind of them, like ... -selector
+                    {[data-property='value']} or ... -selector
