[BUG] kwargs modified during iteration in the DictSerializerMixin

[V3ntus]

Describe the bug.

This seems to be invoked inconsistently and I'm not quite sure what triggers it

List the steps.

• This first originated from a simple ctx.send with an embed

What you expected.

Normal operation

I would not be surprised if its the fault of __setattr__

(I swear I never encountered this while testing)

It seems like EmbedFields are converting from objects to json during iteration somehow?

Using this code to test: api/models/misc.py:40-53

log.debug(kwargs)
try:
    for key in kwargs:
        if key in self.__slots__ if hasattr(self, "__slots__") else True:
            # else case if the mixin is used outside of this library and/or SDK.
            setattr(self, key, kwargs[key])
        else:
            log.info(
                f"Attribute {key} is missing from the {self.__class__.__name__} data model, skipping."
            )
            # work on message printout? Effective, but I think it should be a little bit more friendly
            # towards end users
except: # noqa
    log.critical("HIT")
    log.debug(kwargs)

y e a h

__setattr__ in the embed class

but again, when I tested it worked fine

[V3ntus]

but again, when I tested it worked fine

This is an edge case. Another embed (with a single field) works

[EepyElvyra]

I had multiple fields tho
