JSX render function warning broken in production build

[alexbakerdev]

Describe the bug

Using vite build on the create vite-app (with and without updating vite version) with jsx produces a build that doesn't run, throwing error:
Uncaught TypeError: Cannot read property 'MODE' of undefined at index.fb79c190.js:1

This line is included in the dist output:

"development"===import.meta.env.MODE&&console.log("[vue tip] You are using an non-optimized version of Vue 3 JSX, which does not take advantage of Vue 3's runtime fast paths. An improved JSX transform will be provided at a later stage.")

Removing this line from assets/index.[hash].js allows the app to run as expected.

Reproduction

2. yarn build
3. npx serve dist

open web page its blank, console logs an error

Uncaught TypeError: Cannot read property 'MODE' of undefined at index.fb79c190.js:1
