Using Content Size Fitter or Vertical Layout Group causes error

UI

-

When using the Content Size Fitter OR the Vertical Layout Group components on the Content of a Scroll View, and playing the scene an error pops up:

Trying to add (Layout Rebuilder for) Content (UnityEngine.RectTransform) for layout rebuild while we are already inside a layout rebuild loop. This is not supported.
UnityEngine.Canvas:SendWillRenderCanvases()

2. How we can reproduce it using the example you attached:
See the attached video.

1. Create a Scroll View add Text GO to its Content
2. Add the Content Size Fitter component on the Content
3. Press play
4. Notice the error. Exit play mode
5. change the attributes of the content fitter: Fit - minimum size
6. play again
7. Notice the content size is now fixed
8. set the attributes of the content fitter: Fit - Unconstrained
9. play again,
10. the content size is still fixed

    I was also having this issue with a Scroll Rect + Grid Layout Group and dynamically adding buttons. I was able to do a small workout for the time being by adding a Content Size Fitter and setting both to Preferred Size. Not sure how it will work with multiple buttons though.

    I can confirm that since updating from 5.2 to 5.3 I am getting the same error: Trying to add (Layout Rebuilder for) Content (UnityEngine.RectTransform) for layout rebuild while we are already inside a layout rebuild loop. This is not supported.
    UnityEngine.Canvas:SendWillRenderCanvases()

    It's not just ScrollViews, It happens when you have a ContentFitter inside of a VerticalGroup/HorizontalGroup.

    Really annoying. I had to make some tweaks with my Game Objects since upgrading and I'm not sure if it was cause of this error or not. I'm hoping that that was the most damage this error causes or that it gets solved before my deadline.
