### 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

			if (name == "arg_count") {
				r_ret = args.size();
				return true;

			if (name.begins_with("args/")) {
				int idx = name.get_slice("/", 1).to_int();
				ERR_FAIL_INDEX_V(idx, args.size(), false);
				String what = name.get_slice("/", 2);
