Steps to Reproduce the problem

Base your steps off of any freshly installed react-static template!

1. I have a page that reads window.location?.search
2. I navigate to that page with query-string parameter /xxx?invite=test01
3. On yarn dev or yarn build && yarn serve everything works fine.
4. On yarn build and deploy to production, /xxx?invite=test01 gets redirected by react-static to /xxx. This happens for all pages and all query-string parameters except index page.
