Move cursor not showing if Dialog is not resizable

Current behavior
If resizable={false} is passed as a prop to a Dialog component, the move cursor is not shown when one hovers above the dialog header.
On the other hand, passing draggable={false} has no effect on the move cursor at all.
This most probably is due to the cursor: move; css property being put in the wrong css class (.p-dialog-resizable):

Expected behavior
The move cursor should not be shown only when dialog movement is disabled via the draggable={false} prop.

Minimal reproduction of the problem with instructions
Pass resizable={false} to any Dialog component.
