Retain Corner Radius when freely resizing and changing the rations of a shape

I am trying to get illustrator to retain the corner radius (anchor points) when I scale a shape including when I 'distort' it from its original shape. But InDesign and XD do this.

For example:

I draw a fat rectangle, I use the corner anchors to curve the corners, I then decide to make the rectangle thinner (not proportionally), the corners are now warped into strange curvatures, and some have lost their anchor points altogether. This applies to 4 sided closed path shapes of all varieties, and also to open path sections such as L or U shapes.

I am almost certain this used to be possible within illustrator.
