What happened?

As of PR #9640, WebdriverIO's typings include two copies of the Browser type, one a global type within the WebdriverIO namespace and one a type primitive exported from the module.

PR #10447 made an update to to the primitive export, but not the global namespace version.

In practice, this means that code which tries to use import type { Browser } from 'webdriverio' is incompatible with webdriverio functions that return WebdriverIO.Browser, such as remote.

What is your expected behavior?

The two copies of the type should match, ideally with one defined in terms of the other to avoid this issue in the future

How to reproduce the bug.

// repro.ts
import { type Browser, remote } from 'webdriverio';

async function main() {
    let browser: Browser; // works if using WebdriverIO.Browser instead

    browser = await remote({
        capabilities: { browserName: 'irrelevant' }
    });
}

$ npm init -y
$ npm install webdriverio@8.15.10 typescript@5.2.2
$ npx tsc --noEmit --skipLibCheck ./repro.ts

Relevant log output

repro.ts:7:5 - error TS2740: Type 'Browser' is missing the following properties from type 'Browser': sessionStatus, sessionNew, sessionEnd, sessionSubscribe, and 25 more.
