### 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

String text;

		text += "(";
		Vector<Variant> args;
		if (d.has("args")) {
			args = d["args"];
		}
		for (int i = 0; i < args.size(); i++) {
			if (i > 0) {
				text += ", ";
			}
			text += args[i].get_construct_string();
		}
		text += ")";
		int limit = MAX(0, p_clip_right - p_x - icon_to_draw->get_width());
		if (limit > 0) {
			draw_string(font, Vector2(p_x + icon_to_draw->get_width(), int(get_size().height - font->get_height(font_size)) / 2 + font->get_ascent(font_size)), text, HORIZONTAL_ALIGNMENT_LEFT, limit, font_size, color);
		}
	}
