Resizing GIF causes messed up image

Using following code
var img = Image.Load("C:\\Test\\Editor.gif"); img.Resize(401, 281, ResizeType.LanczosResample); img.Save("C:\\Test\\out.gif");

With following image
Editor.gif (251.6 KB)

produces this output
error1.gif (187.2 KB)
The first frame seems fine, but for the following the buttons near the top are completely messed up.

Removing ResizeType.LanczosResample produces a somewhat better result, but still not as expected.
error2.gif (104.3 KB)

Saving as webp produces even more messed up result where even the hearts are out of place.
