IE 10 Won't Submit Form After jQuery File Upload

We're trying to track down what is described as a "security" issue with IE 10 after a jQuery HTML5 Upload.

After you call the jQuery File Upload Plugin (https://github.com/blueimp/jQuery-File-Upload) with Internet Explorer 10, you cannot subsequently submit the entire form by JavaScript with a single click. It takes multiple clicks to cause a postback.

This behaviour does not occur in the latest versions of FireFox or Chrome.

Could someone from the IE team provide details on what's going on here along with some guidance on how to deal with it?

The current workaround is to treat IE 10 as a downlevel/non-HTML5 browser.

Another possible workaround is to have JavaScript send multiple .Submit() commands until one catches.

Thanks for any input.
