### Godot version

543750a1b3f5696f9ba8e91cb49dc7db05d2ae62

### System information

Windows 10, Vulkan

### Issue description

This is a regression since v4.1.dev4.official [5c2295ff5], I can't bisect atm to find the commit that caused it, maybe https://github.com/godotengine/godot/pull/77651 but that's just a guess.
When a HBoxContainer has a label child, and that label's text is changed, one used to be able to find the new size of the container by using call_deferred, this is no longer the case.

MRP correct behavior (v4.1.dev4.official [5c2295ff5]):

### Steps to reproduce

```gdscript
extends Control

@onready var h_box_container: HBoxContainer = $HBoxContainer
@onready var label: Label = $HBoxContainer/Label

func _ready() -> void:
	label.text = "larger non default text"
	print("h_box_container size.x: ", h_box_container.size.x)
	call_deferred("size_after_text_changed")

func size_after_text_changed() -> void:
	print("deferred h_box_container size.x: ", h_box_container.size.x)
```
