Issues noticed:

1. When two or more draggable list items are frozen either on top or at the bottom, the gap between the items vanishes and they stick together.
2. The drag experience is not smooth. Dragging an item towards the bottom pusher it above the item before it.
3. For frozen items we see the same cursor icon that we see for unfrozen items. This can be confusing for the users.

@shadabbuchh issue 1 is resolved. Issue 2 already exists in the prod.

For issue 3, it is a widget-specific issue i.e. the cursor is managed by the widget that is using it. So I will make changes to the main PR specific to the table widget.

All issues are fixed.

@keyurparalkar the sticky property now does not shift the list item to the top/bottom based on what value we have given.

All issue are fixed. The new isDragDisabled property is working as expected.
