Logs (Optional if provided reproduction)

[plugin:vite:import-analysis] Failed to resolve import "jsuites/dist/jsuites.css?commonjs-require". Does the file exist?

ps: when looking into the actual file, there's an extra question mark character in front of jsuites/dist/jsuites.css?commonjs-require, which I think causes the error, but don't know why it's added.

Except #1568, you should include jsuites at optimizeDeps.
