Steps to reproduce:
1. Create the following .html file and go to the page in Chrome or Firefox:
2. Click inside the first <input> to pop up the datePicker.
3. Scroll down so that the picker is partially obscured like in this image:
4. Select a date.
The expected behavior is that the pickDate will disappear, and the <input> will contain the selected date.
Instead in Firefox, selecting a date causes the datePicker to reappear below the <input>. In Chrome the datePicker will reappear below the <input> for a moment and disappear afterwards. In both cases the input will not contain the text of the selected date.
