Staging individual line of consecutive changes results in wrong ordered lines in patch

[choenig]

Describe the bug

When you change multiple consecutive lines and then try to stage just the first change, this results in the wrong patch.

To Reproduce

Steps to reproduce the behavior:

1. Take the following file:

int main() {
	// init something
	int i = 0;

	return 0;
}

2. Update it to:

int main() {
	// init variables
	int x = 0;

	return 0;
}

3. Now in LazyGit try to only stage the comment-line:

4. The actual result

The lines are shuffeled:

Expected behavior

The comment should be staged without changing the order of the lines:

(This has been done with git-gui)

Version info:

commit=, build date=, build source=Homebrew, version=0.57.0, os=darwin, arch=arm64, git version=2.52.0

I already tried to find a duplicate of this one but failed, maybe due to the keyword I was using ;)

Interesting, I'll have a look at what special logic git gui contains to achieve this. In our defense, Fork has the same problem. (I haven't tried any other git clients.)
