DatePicker incorrect behavior when navigating using tab key

[lucasbmenezes]

When filling up a form using tab key to skip or to go to the next input, and a DatePicker input is reached, instead of continue to the next input field it returns to the first focusable element on the page.

In our demo page, when I hit the Tab key, the focus moves to the next focusable element, and it does not return to the first focusable element.

I couldn't make it work on http://gwtbootstrap3.github.io/gwtbootstrap3-demo/#datePicker. Chrome V49 and Safari V9.

Here are the SS.

DatePicker opened > Tab key pressed

This get focused and it shouldn't. The right one is the "Position" input below the "Setting Languages" input.

I've tested with Firefox 45, it seems it works. But you are right, on Chrome 49, it does not work
