Generating umd or iife bundle not working with vite@2.9.14

[kingcw]

Generating umd or iife bundle is working with vite@2.9.13, but not working with vite@2.9.14

error is:
[unocss] does not found CSS placeholder in the generated chunks, this is likely an internal bug of unocss vite plugin

error is found in this file, line 195. problem code block should start at line 180:

I'm actually seeing this issue with vite@2.9.13 too.
Downgrading unocss to 0.42.1 seems to fix this for me.
