Prettier can't differentiate classic HTML files from Django HTML templates

[ddahan]

Summary

I can't prevent Prettier to run with Django HTML files, while I want to use it with "classic" HTML files only. I don't want to use Prettier to format Django HTML files, because it can't do it and write error in logs if it tries to. Both files have an .html extension and I guess Prettier uses this extension to lint or not.

However, VS Code itself is able to differentiate them after installing a specific extension that add django-html language:

Steps To Reproduce:

1. in your settings: write:

"editor.formatOnSave": true,
"[html]": {"editor.defaultFormatter": "esbenp.prettier-vscode"},
"[django-html]": {"editor.defaultFormatter": null },

2. install this extension

Expected result

When I save a Django HTML file, I expect Prettier not to be run.

Actual result

Prettier is run, and write an error in logs, since it's unable to parse Django tags.

A workaround that does the job:

"[django-html]": {
            "editor.formatOnSave": false
        },

However, I still don't understand why the initial code does not work.
