Unexpected HTTP request to the localhost when empty string is given as src

[peecky]

$ cat temp/test.js 
import probeImageSize from 'probe-image-size';

(async () => {
    try {
        const result = await probeImageSize('')
        console.log({ result });
    } catch (err) {
        console.error(err);
    }
})();

$ node temp/test.js 
Error: connect ECONNREFUSED 127.0.0.1:80
    at TCPConnectWrap.afterConnect [as oncomplete] (node:net:1636:16) {
  errno: -111,
  code: 'ECONNREFUSED',

}

It's better to throw error quickly instead of requesting to the localhost.
