Not linting markdown files

[arvigeus]

vscode-eslint version: 2.1.1
eslint version: 6.8.0
vscode version: 1.42.1

settings:

{
  "editor.codeActionsOnSave": {
    "source.fixAll": true
  },
  "javascript.validate.enable": false,
  "typescript.validate.enable": false,
  "eslint.lintTask.enable": true,
  "eslint.probe": [
    "javascript",
    "javascriptreact",
    "typescript",
    "typescriptreact",
    "html",
    "vue",
    "markdown",
    "md"
  ]
}

file.md (note: there is a zero-width whitespace in this code sample to "escape" the backticks)

​```js
let x;
if ((x = 0)) { }
​```

Running eslint (with markdown plugin installed) correctly displays warnings, but editor shows nothing.

@arvigeus can you please provide me with a GitHub repository I can clone that demos what you are experiencing.

npm run lint works as expected. The errors are not shown in the editor when file.md is open. eslint.probe is set to markdown and md

Actually, probing for markdown is not working correctly right now. You can force markdown linting using

  "eslint.validate": [
    "markdown",
    "md"
  ]

You can deprecate probe in the future: eslint/eslint#10828

I don't think so. What I want to avoid is that I load eslint extension and server for files that can definitely not be linted by ESLint (for example java).
