SingleFile collection method no longer clears on model update

[m7vm7v]

Has there been an update on this functionality recently? I am sure that used to work differently.

In my model I have

    public function registerMediaCollections(): void
    {
        $this->addMediaCollection('main')
            ->withResponsiveImagesIf(true)
            ->singleFile();
    }

And in the controller $this->model->addMedia($validated['image'])->toMediaCollection('main');.

I would expect that when I am updating the model the original collection 'main' that has only 1 file allowed to be deleted and the new one be uploaded and swapped and as far as I remember it used to work that way - please, correct me if wrong. But now the new file is added to the main collection and the database model record does not get updated with the new 'main'. It does start working as intended once I added $this->model->clearMediaCollection('main');. My impression is that using the singleFile method should call the clearMediaCollection automatically.

Any suggestion on what might have been updated and what I might have missed?
