Could you add an extra blank line before this?
(See other comment: 2 blank lines.)

Done.

This macro looks fine;
there's overlap with the getter_callback,
but it's clearer to have a separate one,
instead of cramming them together.

+{% filter conditional(attribute.conditional_string) %}
+static void {{attribute.name}}ConstructorGetterCallback{{world_suffix}}(v8::Local<v8::String> property, const v8::PropertyCallbackInfo<v8::Value>& info)
+{
+    TRACE_EVENT_SET_SAMPLING_STATE("Blink", "DOMGetter");
+    {% if attribute.deprecate_as %}
+    UseCounter::countDeprecation(callingExecutionContext(info.GetIsolate()), UseCounter::{{attribute.deprecate_as}});
