Press enter in mass update due date = wrong action

[nike.stars]

As subject, when in client profile page and i try to check all the products i want to mass update for due date and after that if i press "Enter" it would result wrong action being executed.

 

instead of doing submit for mass update action, the "Enter" key result for items i've checked to have invoices being generated.

 

If i click tha submit button under Mass Update with mouse, it would do just fine
