ConversionCollection::getByName works incorrectly

[maxlapko]

I have multiple collections for my Model with same conversion names

$this->addMediaCollection('landing')
    ->singleFile()
    ->registerMediaConversions(function () {
        $this->addMediaConversion('small')
            ->optimize()
            ->width(150)
            ->height(150);

        $this->addMediaConversion('big')
            ->optimize()
            ->width(1920)
            ->height(720);
    });

$this->addMediaCollection('logo')
    ->singleFile()
    ->registerMediaConversions(function () {
        $this->addMediaConversion('small')
            ->optimize()
            ->width(150)
            ->height(150)
            ->keepOriginalImageFormat();

        $this->addMediaConversion('big')
            ->optimize()
            ->width(500)
            ->height(500)
            ->keepOriginalImageFormat();
    });

I have uploaded png file to logo collection and try to get conversation

$model->getFirstMediaUrl('logo', 'small');

expected png file http://localhost:8000/storage/31/conversions/photo-small.png
got jpg file http://localhost:8000/storage/31/conversions/photo-small.jpg

The problem:
class ConversionCollection::getByName line 42:
$conversion = $this->first(fn (Conversion $conversion) => $conversion->getName() === $name);

Why does not use that condition ?
in_array($this->media->collection_name, $conversion->getPerformOnCollections())
