The timer is starting when you move your mouse into the browser even though timer.start() was not called and startManually prop is true. timer.reset() was called in the mount. To fix, I can update my index.js to the React v18 default way. This is just sample code. In my current project, I cannot update to React v18.

Reproduction Steps

1. Use React v17
2. call timer.reset() in componentDidMount
3. move mouse inside browser
4. the timer will start running
