Protocol relative urls are not handled correctly

[ghmcadams]

urls starting with // are equal to http:// or https://, etc and use the current document's protocol instead of specifying one. You can add support for this easily by changing your source code here:

You just need to add the following that that's all:

|| lowerURL.startsWith('//')
