Replace nativeZoom of widgets with disabled autoscaling with 100

The nativeZoom of some widgets currently always has the original native
zoom value, even if autoscaling is disabled for that widget such that
they behave as if their native zoom is effectively 100. With this change
the behavior of those widgets will be fixed as per autoscale disabled
value.
