Types for the experimental.extensions option don't work in 6.18.0=

If I set extensions to true in my prisma config, such as 
export default {
  experimental: {
    extensions: true,
  }
} satisfies PrismaConfig;
export default {
  experimental: {
    extensions: true,
  }
} satisfies PrismaConfig;
The types do not now support an extensions config option at the top level of the object as I would expect. Instead typescript complains, even though the source code clearly shows this is supported: 
function defineExtensionsConfig(config, configInput) {
  if (!configInput["extensions"]) {
    return;
  }
  config["extensions"] = configInput["extensions"];
  debug2("[config.extensions]: %o", config["extensions"]);
}
function defineExtensionsConfig(config, configInput) {
  if (!configInput["extensions"]) {
    return;
  }
  config["extensions"] = configInput["extensions"];
  debug2("[config.extensions]: %o", config["extensions"]);
}
Error: Object literal may only specify known properties, and 'extensions' does not exist in type 'PrismaConfigUnconditional & SchemaEngineConfigClassic'.ts(2353) I am using Prisma ^6.18.0 and TypeScript 5.9

You decided to hold for human wisdom. We'll chime in soon! Meanwhile, #ask-ai is there if you need a quick second opinion.

I can make the error go away by doing something like PrismaConfig & { extensions: Record<string, unknown> } for example, but I would have expected this to be typed, even if it is an experimental setting.

Can you check if you get the same error in prisma 6.19.0 as well?
