Steps to reproduce

create a component with a generic defineModel (or specify a modelValue prop as generic).
use that component with a model modifier.

(or open the repro and run npm run typecheck)

What is expected?

no error.

What is actually happening?

src/App.vue(11,27): error TS2353: Object literal may only specify known properties, and 'modelModifiers' does not exist in type '{ readonly "onUpdate:modelValue"?: (value: string) => any; modelValue?: string; } & VNodeProps & AllowedComponentProps & ComponentCustomProps'.

Any additional comments?

its not caused by 3.x, downgraded to 2.2.12 and observed the same.
edit: actually, its a regression from 2.1.10 -> 2.2.0
edit2: oh that was when generics where added, so prolly not relevant
