AudioStreamInteraktive Setting next stream to self doesnt work

Godot Version

4.3

Question

This was solved by using Godot 4.4 dev.
I did this (4.4-dev7) and I still encountered the same problem.

In this video, I demonstrate the Problem. I think this is a bug, but perhaps I am just missing something, since people in the Topic above have claimed that this worked in the dev versions for them.

To explain the example:
I have 3 debug streams, which are the same 4 notes played at different volume:
Forte, mezzoforte, and piano (which is music language to say loud, medium loud and quiet).
I first show, that the AudioStreamInteraktive works as intended, when I make every stream transition to another one.
Initial: Forte
Forte → Mezzoforte
Mezzoforte → Piano
Piano → Forte

Works as intended.

Then I set the first stream (which is the forte one) to transition to itself, which makes it play exactly once and not loop as it is supposed to do.

Initial: Forte
Forte → Forte

Does not loop.

Note that in Godot 4.3 not even the normal (non-self) transitions worked for me. When I set the Initial clip to anything but the first one, I got an error, that stated that the clip index was higher than clip_count which was still at 0. From this, I conclude that in 4.3 the clip_count was not correctly updated when adding clips in the editor. (If I interpret the error correctly, it is basically an IndexOutOfBounds error.)
All this (And the fact that the new AudioStreams like AudioStreamInteraktive are still relatively new) makes me believe that the feature is still under development, and does not yet fully work. I would create a bug report, but I want to make sure that it is not just me being stupid. Can anyone confirm that this is or is not an issue with the engine?
Thanks in advance.
