Invalid layout for Compare control in Refactor dialog

[basilevs]

Environment:
Version: 2024-09 M1 (4.33.0 M1) (or any other version)
Build id: 20240711-1605
Mac OS (tested) or another platform (happened to me before on Windows and Linux)

Test steps

• Create a project
  • Either a project with two packages and one class
  • or import example.zip
• Move a class to another package
• Click Preview
• Click "Move compilation unit..."
• Click "Example.java - ..."

Expected result

Compare area occupied all available space

Actual result

Compare area has minimum size

Workaround

Click anywhere in the dialog again. As focus changes, relayout happens and the Compare area becomes larger.
