Currently, Angular HTML templates rely on the Angular extension and the HTML extension to coordinate language features. However, when files are marked as Angular, the vscode-html-language-server is not started by the HTML extension, making it impossible to combine Angular Tree-sitter grammar (syntax highlighting) with features provided by the HTML Language Server.
Starting the HTML language server directly from the Angular extension would allow Angular templates to benefit from both Angular-specific highlighting and full HTML language support, without relying on cross-extension activation behavior or language ID limitations.
