undefined error due to curCSS function

Hi,

there seems to be a critical issue where when using jquery_update v7.x-3.0-alpha3, we have done the following, but are getting an undefined error message. Below is the error message and this is blocking lots of pages as they rely on jquery to load properly, but it does not. We need an option to either update to jquery v2.2+, v3.x+, or this issue needs to be resolved through the module if possible.

Error messaged caused by (line 5559 jquery.js when using uncompressed):

// Support: IE9
// getPropertyValue is only needed for .css('filter') (#12537)
if ( computed ) {
ret = computed.getPropertyValue( name ) || computed[ name ];
}

Console error message:

"undefined" and it generates a URL of "site.com/en/undefined" which is accessible by google bots and other bots that crawl sites.
