### Godot version

4.2 dev3

### System information

Windows 10.0.19045 - Vulkan (Forward+) - dedicated NVIDIA GeForce GTX 1060 (NVIDIA; 30.0.15.1403) - Intel(R) Core(TM) i7-7700HQ CPU @ 2.80GHz (8 Threads)

### Issue description

If you have a Method Track with multiple calls to the same method, they are joined together and makes things unreadable:

The horizontal line shouldn't be used here. I think it might be a regression.

### Steps to reproduce

1. Add AnimationPlayer
2. Add a Method Track (with Add Track button)
3. Add some key to the track
4. Add another key with the same method

### Minimal reproduction project

N/A
r_base_path = NodePath();
	ERR_FAIL_COND_V(!animation.is_valid(), PropertyInfo());
	ERR_FAIL_INDEX_V(p_idx, animation->get_track_count(), PropertyInfo());
	if (!root) {
		return PropertyInfo();
	}
	NodePath path = animation->track_get_path(p_idx);
	if (!root->has_node_and_resource(path)) {
		return PropertyInfo();
	}
	Ref<Resource> res;
	Vector<StringName> leftover_path;
	Node *node = root->get_node_and_resource(path, res, leftover_path, true);
	if (node) {
		r_base_path = node->get_path();
	}
	if (leftover_path.is_empty()) {
		if (r_current_val) {
			if (res.is_valid()) {
				*r_current_val = res;
			} else if (node) {
				*r_current_val = node;
