Rectangle does not re-render properly after transformation in react-konva

Question

I have been using this ( https://github.com/oasis10702/konva-simple-example ) code in a project of mine and everything works fine. However, updating react and react-konva to the latest version causes some to me unintended behavior. When resizing a rectangle with the transformer, it is scaling the border stroke, see image. scaleX and scaleY doesn't either seem to reset which make it perform the scaling every time i move the rectangle.

I'm new to both React and Konva and wonder if there is some logic that have changed during the new versions that I should consider to mitigate this.

Try to resize the rectangle in the below sandbox. https://codesandbox.io/embed/vyv106x295 If I update the dependencies to the latest, the behaviour becomes changed.

I've tried solving it with https://github.com/konvajs/konva/issues/401 but it doesn't seem to help in this version.

The main change was the strict mode. You can just enable it back for all shapes, or just one rectangle:

<Rect {...someProps} scaleX={1} scaleY={1}  _useStrictMode />
