How to reproduce:
1. Open the attached project (ReorderableListTest.zip)
2. In the Project window, under Assets, select ReorderableListTest 1
3. In the Inspector window, expand Element 0, then expand "Nest Me" under Sub Criteria
4. Select the Helper Functions (tool icon) under Nest Me
5. Select "Nest in new Composite"
6. Observe the Inspector UI

Expected result: top parent element expands to the new height of all of its children, no overlapping UI elements
Actual result: top parent element maintains its old height, causing children to overlap elements as they extend beyond the parent's layout

Reproducible with: 2020.2.0a13, 2020.3.30f1
Not reproducible with: 2019.4.37f1, 2020.2.0a12, 2020.3.31f1, 2021.2.16f1, 2022.1.0b13, 2022.2.0a8

2. In 2022.1.0b13 and 2022.2.0a8, no errors are thrown and the UI is drawn correctly
