I am having the same problem now and am on 9.2 with the latest updates…seems bug has been reintroduced. Grid on its own fits in the window, but when I add it as a nested grid, does not wrap at all and goes way off the screen. The master application is the same way in these pics. Both fit fine on their own, but when building a nested grid, the width settings are no longer adhered to.
