Select description gets attached to multiple field

[tim-x-y-z]

In the demo here if we add a description to the first select as:

class SelectForm(BaseModel):
    select_single: ToolEnum = Field(title='Select Single', description="First selector")
    select_multiple: list[ToolEnum] = Field(title='Select Multiple')
    search_select_single: str = Field(json_schema_extra={'search_url': '/api/forms/search'})
    search_select_multiple: list[str] = Field(json_schema_extra={'search_url': '/api/forms/search'})

it produces the following, where we can see the description leaking to the next select:

However, I noticed that if I use a different Enum for the second selector this does not happen; e.g:

class ToolEnum2(str, enum.Enum):
    hammer = 'hammer'
    screwdriver = 'screwdriver'
    saw = 'saw'
    claw_hammer = 'claw_hammer'

class SelectForm(BaseModel):
    select_single: ToolEnum = Field(title='Select Single', description="First selector")
    select_multiple: list[ToolEnum2] = Field(title='Select Multiple')
    search_select_single: str = Field(json_schema_extra={'search_url': '/api/forms/search'})
    search_select_multiple: list[str] = Field(json_schema_extra={'search_url': '/api/forms/search'})

Note: adding a description to the second select in the initial case doesn't work either, the first description still keeps it spot:

class SelectForm(BaseModel):
    select_single: ToolEnum = Field(title='Select Single', description="First selector")
    select_multiple: list[ToolEnum] = Field(title='Select Multiple', description="Second selector")
    search_select_single: str = Field(json_schema_extra={'search_url': '/api/forms/search'})
    search_select_multiple: list[str] = Field(json_schema_extra={'search_url': '/api/forms/search'})

my 2 cents; I believe the description gets attached to the components by it's name and the component name is derived by the Enum name - though i am unsure how to solve it for now

Thanks for reporting, this looks like a bug.

Based on the output from the follwing the bug doesn't seem to be in Pydantic, but rather in FastUI.

PR welcome to fix this
