Repeater fields for files broken on IE9

[roborourke]

The 'Add file' button just refreshes the page.

Steps to recreate:

1. Register a file upload repeating field
2. Browse to post edit screen in IE9
3. Click 'Add new'
4. Click 'Add file' button that appears
5. Page refreshes

So, it works fine on WordPress 3.9.3 , then on 4.0.1 it starts to break, and then on 4.1 it's completely broken.

@pdewouters could be jquery version changing?

If I enqueue the scripts on edit_form_advanced or edit_form_after_editor it fixes the issue ( except for the large button ) but the uploader works. It seems to be a problem with enqueuing on admin_enqueue_scripts for some reason.

No that's not the issue, sorry.
