Steps to reproduce

const [modelValue, modifiers] = defineModel<string, 'trim' | 'uppercase'>();

// @ts-expect-error
if (modifiers.trim) {}

What is expected?

modifiers type should be a Record or undefined

What is actually happening?

modifiers type is always a Record, but its runtime value can be undefined. So either fix modifiers type or use an empty object as a fallback?
