Unable to serialize model after calling registerMediaCollections

[spycrabo]

Version of package: 9.4.2

InteractsWithMedia trait defines public array $mediaCollections attribute. The registerMediaCollections method filling this array with MediaCollection instances. Each instance initializes mediaConversionRegistrations and acceptsFile with closures in constructor.
So in case when working with eloquent model serialization (in my example I'm storing models in cache) and model is "fresh" (registerMediaCollections method was not called) model can be serialized and all works properly.
But if I want to serialize model after registerMediaCollections method was called I'm getting error "Serialization of Closure is not allowed" because of closures in MediaCollection instances.

I think this attributes should not be serialized and method __sleep() or __serialize() should be defined in MediaCollection class. Or may be I'm trying to use it wrong?
