Optionally make CSS reference/asset resolution failures errors instead of warnings?

[Mr0grog]

I have a build in which I’d like to ensure all the asset references in my CSS successfully resolve. At the moment, I get a warning like:

../../static/img/strikethrough.svg referenced in ../../static/img/strikethrough.svg didn't resolve at build time, it will remain unchanged to be resolved at runtime

…which is great, but the exit code is 0, and this is just a warning. Is there any way to make Vite treat this as an error instead? I’ve looked through the documentation and, if there’s an option, I’m certainly missing it!

(Obviously I can work around it my capturing stderr and grepping for the problems I’m concerned about… or maybe failing if there’s anything on on stderr, but it would be nice if I didn’t have to do that. As-is, I need to at least be careful about debug output on stderr. Not sure if there can be other non-warning/error output on stderr.)
