Affected version

4.2.3

Description of the problem

The overlay of component can be hidden in some cases. For example:

I use this component inside of Vaadin's Dialog. This dialog has strict height and can not be resized in any ways. DateRangePicker is located near the bottom of Dialog, and overlay is being hidden on opening, so i need to scroll down to make any changes to date range.

If you check Vaadin's overlay (ex. on ComboBox opening), it opens above any elements and not being hidden by any. I think, this component's overlay should inherit the same behaviour.

when overlay is opened

so scroll is needed

Steps to reproduce the bug

1. Add DateRangePicker to a container with strict size.

height: 100px;
overflow: scroll;

2. Open an overlay;
3. Overlay's content is being limited by container's size

Additional information

Here is the example of Vaadin's ComboBox when overlay is opened
