Swagger-UI ignoring explore url

[dpeger]

When entering a custom URL into the explore URL field on http://petstore.swagger.io/? this URL will completely be ignored and swagger-ui will always use http://petstore.swagger.io/v2/swagger.json as API spec source.

One can provide a custom URL by adding the url=<custom-swagger-spec> query parameter (e.g. http://petstore.swagger.io/?url=https://github.com/swagger-api/swagger-ui/files/832086/swagger.yaml.txt) but when pressing Explore, swagger-ui will again user the petstore specs.

I'm having a similar issue (updating the URL and then pressing explore resets the URL back to the petstore). I've done some digging and it looks like the downloadUrl function in plugins\topbar\topbar.jsx needs modifying:

downloadUrl = (e) => {
  this.props.specActions.updateUrl(this.state.url)
  this.props.specActions.download(this.state.url)
  // This line is needed to prevent the form submission from refreshing the page
  e.preventDefault();
}

Just merged the PR for this - the fix will be released as part of our release tomorrow.

Thanks for the input, everyone!
