multi route SSG

[CharlesJu1]

Describe the bug

I have a simple app with two routes / and /pricing. I configured to generate for both routes. In dist, index.html and pricing.html are generate. Both are prerendered with correct html content. Then I run npm run preview. When visiting / and /pricing, the browser displays ok. when visiting /pricing.html, the browser is blank. From devtool, I can see that when visiting /pricing.html, the pricing.html file is fetched over network. But it is showing blank. When visiting /pricing, it gets the same /pricing.html file (index.html is not fetched), but displays ok. I verified with curl that in both cases the request returns the same file. Also the devtools network tab shows the same set of requests are sent for the bundled js, css, and detector.js.
