openBrowser can't open url of SPA  

```
const openBrowser = require('react-dev-utils/openBrowser')
const url = 'https://example.com?lattest=22&lngtest=33'
openBrowser(url)
```
I want to open url 'https://example.com?lattest=22&lngtest=33', but actually the url of opening tab is
'https://example.com/?lattest=22'
