Default props do not work in the way as MyComponent(props = {}).
Rather, it's more recommended to set the props property of the functional component https://vuejs.org/guide/extras/render-function.html#functional-components
MyComponent({ msg = 'hello' }) works, too.

It is also widely recommended to enable the default-param-last rule of ESLint (both Airbnb and Standard style guides recommend so).
So the example in the issue is an anti-pattern anyway.
