Container has wrong size when it appears after expanding

[KoBeWi]

Godot version

3.x a76316c, does not happen on master

System information

W10

Issue description

The size after appearing was the size I gave the container originally. I then duplicated the contents and after toggling visibility, it doesn't restore the expanded size, but the old one.

Steps to reproduce

1. Create a container and give it some size
2. Put miltiple controls inside the container, so that it expands
3. Toggle visibility of the container twice
4. The container will appear with its original size

Minimal reproduction project

Duplicate the TextureRects and toggle visibility of root.
