nit:
I would do either:
{% if field.field_template in ('storage_only', 'monotonic_flag', 'external') %}
or
{% if field.has_protected_methods %}
and hide the logic in the generator.

Went with option 1

+  {{field_templates[field.field_template].decl_protected_methods(field)|indent(2)}}
+  {% endif %}
+  {% endfor %}
+
   ~ComputedStyleBase() = default;
 
   // Storage.
   {% for field in fields %}
   {% if field.is_bit_field %}
   unsigned {{field.name}} : {{field.size}}; // {{field.type_name}}
   {% else %}
   {{field.type_name}} {{field.name}};
   {% endif %}
   {% endfor %}
 };
 
 } // namespace blink
 
 #endif // ComputedStyleBase_h
