[VerticalLayoutGroup] Children position is not updated when a child's scale is animated



How to reproduce:
1. Open user's attached "VerticalLayoutGroup -" project
2. Open "SampleScene" Scene
3. Enter Play Mode
4. Observe the Scene view (More visible than in Game view)

Expected result: Both "Left Panel" and "Right Panel" GameObject's children change position according to size and scale change when size/scale is changed manually or animated
Actual result: "Left Panel" GameObject's children move according to size change when animated, but "Right Panel" GameObject's children stay in the same place, even though the first child's scale is getting animated and "Use Child Scale" property on "Height" is checked on the VerticalLayoutGroup Component

Reproducible with: 2018.4.24f1, 2019.4.3f1, 2020.1.0b15, 2020.2.0a17

- Having "Use Child Scale" property unchecked on "Height" and changing the scale manually looks the same as the behavior when a child's scale is animated, so this property might not be respected when animated
- When changing manually the first child's scale, other children move accordingly to the scale change
- Attached a video showing the behavior of changing the scale manually and when it is animated

  1. Resolution Note (fix version 2021.2):

    Added a note to documentation to say Animation is not supported when modifying the scale.(Overall the issue is by design)
