css transform does not end when css is lacking a closing bracket in selector

[sapphi-red]

When input css has an invalid syntax (lacking a closing bracket in selector), esbuild transform does not end.

For example:

:where( {}

and

:where(blockquote, :not(ltr) {
  border-left-width: 3px
}
:where(blockquote, :not(rtl) {
  border-right-width: 3px
}

Original issue: vitejs/vite#8034
My thoughts: vitejs/vite#8034 (comment)
Reproduction: stack blitz (node esbuild.js)

Thanks for the report! Sorry about that. I'll fix this in the next release.
