Comment indentation shifts

## Steps

1. Visit https://stackblitz.com/edit/vitejs-vite-bcqtrm?file=x-component.ts
1. Note the comment's indentation.
1. Run `npm run format:component`.

## Expected

Comment indentation is unchanged.

## Actual

Comment is partly indented to the left and indents further with each `npm run format:component`. Compare with `npm run format:styles`, which does not use `postcss-lit`.
