Grid display is misaligned with the window

### Description

The WPF window does not look the same in design mode as it does when built.

The window style is `SingleBorderWindow `or `ThreeDBorderWindow`.

I don't know if this will be a problem in `ToolWindow `style

### Reproduction Steps

Create a WPF project and build.

You can add a test label.

### Expected behavior

The contents on the right and bottom are displayed completely.

### Actual behavior

The content on the right and below is incomplete or cropped.

### Regression?

I didn't test the older version.

### Known Workarounds

Use the `None` window style.

### Impact

_No response_

### Configuration

.NET 6 to .NET 9

Windows 10 22H2, Windows 11 24H2

Any CPU
