Steps to reproduce

I'm not sure why in the linked project I don't have any type errors, but I get them locally when running the same code example. If you have a named defineModel with required: true and try to pass it via kebab case to the child component, typescript complains that property-a isn't being passed. It does say that propertyA is being passed. I noticed that only the v-model props are being expected in kebab-case, the others are expected in camelcase.

I was also having additional runtime problems with kebab casing, but these were resolved in version 3.5.12. It seems the typescript issue is a lingering problem.

What is expected?

I called defineModel with the string property-a and I expect to be able to pass v-model:property-a.

What is actually happening?

Vue 3's compiler is turning v-model:property-a into the prop propertyA but the child component type is expecting property-a. The expected prop names for other declared props are all camel-cased.

Any additional comments?

One workaround is @vue-ignore, another is to only use single-word v-model names.
