Steps to reproduce

A minimum scene tree:

Control
    TabContainer
        Control
            Label
        Control
            Label

Where the labels have the same position according to Layout/Transform.

74653_demonstrator.zip should be a minimal reproduction.

Yeah, and I'm pretty sure this was reported already, but I can't find it. So we can keep this one for now.

Still happens in 4.1.1 stable .
need to change current tab value to correct tab to trigger sort_children

[KoBeWi]

The minimal project is empty. There are no scenes.

Here is an MRP:

TabContainer_74653.zip

Steps:

1. Open control.tscn.
2. Use the toggle visibility button in the Scene dock to show the ColorRect or the TextureRect.
3. The ColorRect doesn't show at all, and the TextureRect appears at the wrong position and scale.
4. Use the TabContainer's current tab property in the Inspector to see what they should look like.
5. After that, they will be correct when changing visibility, so close and reopen the scene to reproduce again.
