Jinja2 templates in SQL/JSON injected into YAML

I have a bunch of YAML files that include both JSON and SQL as text string blocks in PyCharm 2023.1, for example:

# language=json
params: |
  {# language=json #}
  {
    "end_date": {
      "title": "End Date",
      "default": "{{ now() }}"
    }
  }

# language=sql
query: |
  {# language=sql #}
  SELECT *
    FROM my_table
   WHERE created_at < {{ end_date }}

Is it possible for PyCharm to highlight both the JSON/SQL syntax as well as the Jinja2 templates?

These resolved issues seem to imply this should work:

• https://youtrack.jetbrains.com/issue/IDEA-106449
• https://youtrack.jetbrains.com/issue/PY-25277/Support-data-language-for-Jinja2-templates

However I can only get PyCharm to highlight either JSON/SQL OR Jinja2.  

I have JSON, SQL, and YAML set as `Template File Types`, but once I added YAML to that list the JSON/SQL injection comment seems to just get ignored, and only the Jinja2 is highlighted.
