Research direction

Reproduce the issue in a TypeScript file in VS Code with extensions disabled, using import type from './type'. Then inspect the repository's TypeScript TextMate grammar rules for import declarations. Done means type is highlighted as a variable name rather than a keyword in this case, while the surrounding import syntax remains correctly highlighted.
