We’re working on a simpler way to show dimensions between the inspector and the editor.
For now you may want to adjust the parameters in the Inspector first before making any scale edits in the view.
For example: To keep the corner rounding consistent, resize a the "Radius" parameter of a Box using the Inspector. Resizing it in the view distorts the edges, and does not change the base values shown in the Inspector.
Dimensions don’t match what I see in the view
The size shown in the view is just the current outline or bounds of the selected shape.
When you scale a shape in the view, the new size will not match the Inspector base parameters.
