FlowMod Web UI Input Box Focus

When I click the input box in FlowMod dialog, it will lose focus randomly. To reproduce this bug, just choose a input box, click it, and wait. You'll see the focus disappeared. This could be caused by background refresh or something else.

Also I noticed that the dropdown list of FlowMod action has the same issue, too. For example, I select "DEL", then it will turn back to the default value "ADD" after a random time interval. This is quite annoying.
