TextEdit Node Bug - setting node.text = node.text in a signal call node.connect('text_changed', my_func) reverses printout of node.text

### Tested versions

4.2.1.stable

### System information

Godot v4.2.1.stable - Windows 10.0.22631 - Vulkan (Forward+) - dedicated NVIDIA GeForce RTX 3050 6GB Laptop GPU () - 12th Gen Intel(R) Core(TM) i7-12650H (16 Threads)

### Issue description

For a textedit node I am trying to strip newline characters and limit the length to 15 characters (maybe i'll do a feature request for this). While trying to achieve this I noticed that the text always prints backwards. In the MRP I would expect if you set a variable to itself it would not change, however when you run the project you will observe that the text is reversed.

### Steps to reproduce

Create a new project using v4.2.1.stable. Add the script in MRP. Run the project and type 'hello' into the textedit. it will read at 'olleh'

### Minimal reproduction project (MRP)

extends Node2D

var textbox : TextEdit = TextEdit.new()

func _ready():

textbox.size = Vector2(200, 50)
add_child(textbox)
textbox.connect('text_changed', clip_text)

func clip_text() -> void:
textbox.text = textbox.text

Run the provided minimal reproduction project with Godot 4.2.1 and confirm that assigning textbox.text to itself from the text_changed callback reverses the entered text. Start by tracing the TextEdit text_changed signal and text assignment behavior; done means the same assignment no longer reverses the displayed or printed text while text editing still works.
