Vite picking up styles only for root component

Describe the bug

I create a custom element inside which I wrap a multi-components vue application. For some reason, vite ignores the styles of nested components and only inserts the styles of the root component.

In reproduction, expected two lines of text: one red and one green. Actual: two lines of text: one red and one black;
