Problem with DrawPreview in Editor

I’m currently working with the Preview Editor, but there something different with a EditorWindow and Inspector.
Example: i’m using EditorGUILayout to draw a label like this:
9765558--1398972--upload_2024-4-12_7-27-45.png

And the result is:


Why the text is arranging from bottom?

I’m trying to use GUILayout.BeginArea, but this method seem to be doesn’t work in side DrawPreview, the content inside BeginArea has gone away, nothing rendered :frowning:
