Current behavior
Calendar overlay only disappears in ChangeDetectionStrategy.OnPush components, when another change detection runs because the markForCheck on calendar.ts:2077 is outside of zone and doesn't trigger change detection.

Expected behavior
Calendar should work like in ChangeDetectionStrategy.Default components.

Minimal reproduction of the problem with instructions
The provided stackblitz shows a calendar in a default and an onpush component side by side.

• Angular version: >=8
