[ImageEditor] Can't switch brush color when custom colors specified

[halleewong]

Describe the bug

Changing brush colors does not work when specifying custom brush colors. Tried setting the brush color_mode to fixed or defaults and it doesn't make any difference.

I think there is a problem with updating or selecting colors. You can check it after here . Repeatedly selects the first color as the default one when called.

The problem seems to start at 4.39.0. 4.38.1 works correctly. Perhaps something related to #8802?

I am getting an error when I use the gradio version 4.38.1 which is related with pydantic:

pydantic.errors.PydanticSchemaGenerationError: Unable to generate pydantic-core schema for <class 'starlette.requests.Request'>. Set arbitrary_types_allowed=True in the model_config to ignore this error or implement __get_pydantic_core_schema__ on your type to fully support it

Same problem here.

Falling back to 4.38.1 fixed this problem.

+1 you can observe the behavior on the gradio playground
