I have gotten the template comments to show up previously. Not sure what the problem is this time. My development.services.yml file looks like...

parameters:
  http.response.debug_cacheability_headers: true
services:
  cache.backend.null:
    class: Drupal\Core\Cache\NullBackendFactory
    
parameters:
  twig.config:
    debug: true
    auto_reload: true
    cache: false

I cleared all caches. I have tried "view source" in FF and Chrome.

If I dump $settings['container_yamls'] in settings.local.php, I see that Drupal has the right path for development.services.yml. And there are no problems in the status report page.
