Does this issue occur when all extensions are disabled?: Yes

• VS Code Version: 1.97.2
• OS Version: macOS 15.3.1 arm64

Tokenization features such as syntax highlighting still carries on for huge files even if the editor.largeFileOptimizations option is active.

Steps to Reproduce:

1. Get a source code file larger than 100 MB.
2. Enable the editor.largeFileOptimizations settings (it should be enabled by default).
3. On the first open, tokenization features is not active (e.g. no syntax highlighting).
4. On subsequent open, tokenization features will be active (e.g. syntax highlighting active).
