Description

Bug Description:

Languages that support embedded languages in an extension, when editing a part of a file where the embedded language is, IntelliSense doesn't work.

Steps to Reproduce:

  1. Create a HTML file.
  2. Add a SCRIPT tag.
  3. Add some JavaScript code in the tag.
  4. Initiate IntelliSense with Ctrl+Space, in VSCode the language Server is initiated and a list of attributes/functions are displayed, in theia it does not.

Contributor guide

Research direction
Investigate how Theia's language server integration handles embedded language scopes (e.g., JavaScript inside HTML script tags). Look at the Monaco editor integration and the language server client setup to identify why IntelliSense requests fail in embedded contexts.
