Monaco Editor Playground Code

monaco.languages.register({ id: "mySpecialLanguage" });

monaco.languages.setLanguageConfiguration('mySpecialLanguage', {
  autoClosingPairs: [
    { open: "'", close: "'" },
    { open: '`', close: '`' },
  ],
  // autoCloseBefore not helping in this case
});

monaco.editor.create(document.getElementById("container"), {
	language: "mySpecialLanguage",
});

Reproduction Steps

1. type in a word string

2. type a quote (' or ") at the beginning of the string

3. type a quote at the end of the string. only one quote is added.

4. enter into a new line and type a word string

5. type a backtick (`) at the beginning of the string

6. type a backtick at the end of the string. two backticks get added, when there should only be one
