ts-jest: TS: 2339: Property 'xxx' does not exist on type 'CombinedVueInstance>'

🐛 Bug Report

I have a Vue project with Typescript where I also use vue-test-utils. So in order to test components a Wrapper is used. This looks like this most of the time:

const wrapper: Wrapper<InstanceType<typeof SomeComponent>>;
wrapper = mount(SomeComponent, <options>);

it ('test', () => {
  expect(wrapper.vm.someprop).toBe(true);
})

Hence, the wrapper has a pretty extensive type now. But when I run jest, ts-jest is stating that someprop does not exist on type CombinedVueInstance<Vue, object, object, object, Record<never, any>>, but that is not the type of wrapper.vm.

To Reproduce

Steps to reproduce the behavior:

Expected behavior

ts-jest should use the correct type.
