window.open() suddenly started throwing an "Unrecognised Expression" when being called in a function containing just it. I've tried changing URL, and the Javascript file that the function is in to no avail. Has anyone else experienced this? I'm using the latest JQuery CDN, and it's loading well above the Javascript files.

Code:

```
function spotify() {
    window.open("https://www.google.com");
}   

```

Error:

```
Error: Syntax error, unrecognized expression: https://www.google.com
