DemoProject.zip DesignView RuntimeView

When you look at the a WPF form in the VS2019 designer, and when you view the form at runtime, the spacing always seems to be a bit different. Attached a sample project showing the issue, and a screenshot on my PC showing the same form at runtime and in the designer. You can see the amount of space under the OK button is different in both screenshots, and the way the legal wording is wrapped is also a bit different.

Our expectation is that the form would be rendered the same way in the designer and a runtime.
