So we're noticing some slight functionality differences in Forms.  Normally when you try to submit a form with required fields that are not filled out it will auto focus, highlight the field, and show the red text signifying the field is required.  However, if the required field is an upload field, we're noticing that it just shows the red text, it does not highlight yellow or autofocus to form to the field.  We have a customer who has a fairly large form and users are confused because they cannot submit the form but have to scroll through the entire form to go and find the required upload field to upload.  

1.  Is there a reason the behavior is different between field types?

2.  Is there a workaround or way to get upload fields to function the same?

Thanks for any help/ideas on getting things to function the same.
