Incorrect Token Scoping for ⁠defer Keyword in TypeScript 5.9 in VSCode #1058

Description

Type: Bug

With the release of TypeScript 5.9, a new feature supporting the ⁠import defer functionality has been introduced. However, when using VSCode's "Developer: Inspect Editor Tokens and Scopes" to inspect the ⁠defer keyword, it is currently scoped as ⁠variable.other.readwrite.alias.ts instead of the expected ⁠import.control.defer.ts. This issue prevents the proper application of style changes using TextMate.
It seems that the ⁠defer keyword should be correctly scoped under the ⁠import.control.defer.ts range as mentioned above.
Thank you.
