Encontrei o bug! Eu já estava refatorando esse serviço um pouco, então incluí a correção nele:

> <https://github.com/discourse/discourse/pull/33380>
>
> \- Introduce a \`max\_page\_size\` option, allowing different behavior between contro…llers and SDK.
> \- Improve the contract (validations & helper method).
> \- Use \`model\` where possible.
> \- Extract message existence logic to a dedicated policy, allowing easier testing.
> \- Refactor specs to follow current guidelines/best practices.
