Embedded languages use outer language auto-closing characters

• VS Code Version: 1.60.1
• OS Version: OSX 11.6

When a language is embedded, the value of autoClosingPairs is taken from the parent language, not the embedded one. Related to #117190

Steps to reproduce

1. Create a LaTeX file containing

   \begin{cppcode}
      int main() {
        return 0;
     }
   \end{cppcode}
   

2. Check that inside the cppcode environment, we use the cpp embedded language

   

3. Insert ` inside the cppcode environment. It automatically gets closed by '.

   

The latex language configuration adds ["`", "'"] to autoClosingPairs but not the latex cpp embedded language.

Am I missing something? For what it is worth, I am maintaining the LaTeX-Workshop extension.

You’re perfectly correct, all the typing code always uses the outer language characters because of the way this is implemented here.

I confirm that the problem still occur with a US keyboard layout.

In a regular python file, it works fine

according to https://github.com/microsoft/vscode/blob/main/extensions/python/language-configuration.json#L33.

Let me precise the issue. When a language is embedded, the value of autoClosingPairs is not overwritten but instead it still has the value of the parent language.
