TextField.onSetFocus() and tabIndex

hey there - I have a form with numerous input boxes. I’ve set tab orders to tab through the fields. In this scenario, I actually LIKE the edge highlight that appears around the textField when tabbing through them. However, this dissappears for any textFiled that I placed an onSetFocus event.

Anyone know how to retain the border highlight without manually setting border colors on tab through?

Thanks!
