Issue Description

I use Preact and have this in my tsconfig.json:

    "jsx": "react",    "jsxFactory": "h",    "jsxFragmentFactory": "Fragment"

I use it like so:

import{h,Fragment}from"preact";exportdefaultfunctionMyComponent(){return<><h1>Hello, world!</h1></>;}

It used to result in no errors. With version 5.27.0, it reportsh andFragment as unused.

I’ve searched through the issue tracker, and also in TypeScript’s and Preact’s issue trackers, but couldn’t find anything. I apologize if I missed something, or this is a misunderstanding on my side that just happened to work before!
