Datepicker - adaptivePosition does not work when placed in a modal

[learnuser521]

Bug description:
Adaptive Position of datepicker and dateRangePicker do not work when placed inside a modal. When we scroll inside the modal, the datepicker sticks to it's initial position it was opened. When the focus is lost from app browser window, the position updates.

@apotapcukv @learnuser521 - I was wondering if there's any workaround for this? Have you managed to resolve it?
