Overlay: Allow tall modals to overflow the viewport height

[arturhun]

Please describe the feature you would like to request.

Overlay.position() should offer a way to display really tall modals without adjusting their height to max 100% of the viewport/backdrop.

current positioning:

as you see the panel stretches only as tal as viewport permits, thus truncating the contents.

What is the use-case or motivation for this proposal?

There are cases where modal is used to display lengthy information (long lists, rich restaurant menus, etc). In such a case designer often choose to display the modal as tall as need be, rather than displaying a scrollbar. The backdrop height is just auto.

Is there anything else we should know?

• An example of such an implementation can be found at trello.com
• I am mentioning height only, but obviously some users might also want to allow horizontal overflow for different cases.
• If there is a way to achieve that in CDK, please point me to specific place in docs.
