Bug Report

Please answer these questions before submitting your issue. Thanks!

1. Minimal reproduce step (Required)

schema BaseConfig:
    name: str

schema Config(BaseConfig):
    count: int

schema Name:
    config: Config

n = Name{
    config: {
        name = ""
        <cursor>  # cannot complete  for `count`
    }
}

But the following two situations are work

schema BaseConfig:
    name: str

schema Config(BaseConfig):
    count: int

schema Name:
    config: Config

n = Name{
    config: Config {   # specify the schema name
        name = ""
        <cursor> 
    }
}

and

schema BaseConfig:
    name: str

schema Config(BaseConfig):
    count: int

schema Name:
    config: Config

n = Name{
    config: {  
        count = ""  
        <cursor>  #  `count` is attr of Config, `name` is inherited from BaseConfig, lsp can still complete the `name` here
    }
}
