Problem

This is an irrelevant question, but I have always been curious about what caused the inconsistency of the highlighting on both sides🤔 .
Prior to this, I have searched a lot of information and did not find the specific reason.

Reproducible Case

I think it's because the typescript extension has the semantic-highlighting feature. It provides highlights with type analysis.

@jasonlyu123 You are correct, when I set "editor.semanticHighlighting.enabled": false, the display of the .ts file is the same as the display of lang="ts".
