Inconsistent editor movement near arithmetic operators

[1xhitt]

Tested versions

Godot Engine v4.2.1.stable.official.b09f793f5

System information

Linux (Pop!_OS 22.04 LTS)

Issue description

Ctrl + left/right moves cursor inconsistently. It skips some operators and stops at others. This is particularly annoying with + and - operators.

Steps to reproduce

Example code

	num1 = num0 + c1 
	num1 = num0 - c1

Setting the cursor in the line 1 and pressing ctrl + left twice will put it before +. Doing so with the line 2 will put the cursor before num0.

Minimal reproduction project (MRP)

	#moves to the operator
	num1 = num0 + c1
	num1 = num0 ^ c1
	num1 = num0 > c1
	num1 = num0 >= c1
	num1 = num0 <= c1
	num1 = num0 < c1
	num1 = num0 == c1
	num1 = num0 << c1
	num1 = num0 >> c1
	num1 = num0 | c1
	
	# moves to the center of `!=` 
	num1 = num0 != c1
	
	# moves to `num0`
	num1 = num0 - c1
	num1 = num0 & c1
	num1 = num0 * c1
	num1 = num0 ** c1
	num1 = num0 / c1
	num1 = num0 % c1
	num1 = num0 % c1
	num1 = num0 % c1

Please try with 4.2.2 to make sure this still occurs and hasn't been fixed already

Behavior does not change in Godot Engine v4.2.2.stable.official.15073afe3

I would like to be assigned to this issue.

We don't assign people to issues, and the first step would be to identify what's going on and to decide what to do, so if you want to investigate that that'd be great! And report your findings here

• looks related to Double clicking on a word can select prior not character symbol #69254
• possibly fixed by Enable custom separators to treat different characters as words #92514

[kitbdev]

• Now has consistent behavior for all operators after Add missing punctuation to the default TextEdit word separators #93656

However, the caret skips the operator and goes to num0 in the example, when it should stop after the operator. This also affects word delete and word backspace.
