TS2322: Type 'number' is not assignable to type 'SSRSlot'

Expected Behaviour

The error in the pic should not be shown.

Actual Behaviour

when using dynamic slot with v-for with vue components, i'm getting the following errors:

error in /home/michael/Development/app/symfony-demo-vue-bug/assets/vue/components/Parent.vue.ts 8:00:25 AM

[tsl] ERROR in /home/michael/Development/app/symfony-demo-vue-bug/assets/vue/components/Parent.vue.ts(5,93)
TS2322: Type 'number' is not assignable to type 'SSRSlot'.

error in /home/michael/Development/app/symfony-demo-vue-bug/assets/vue/components/Parent.vue.ts 8:00:25 AM

[tsl] ERROR in /home/michael/Development/app/symfony-demo-vue-bug/assets/vue/components/Parent.vue.ts(6,37)
TS2769: No overload matches this call.
The last overload gave the following error.
Argument of type '<K extends string | number | symbol>(slotName: any) => { name: any; fn: Function; }' is not assignable to parameter of type '<K extends string | number | symbol>(value: any, key: K, index: number) => VNodeChild'.
Type '{ name: any; fn: Function; }' is not assignable to type 'VNodeChild'.
`

I tried to create a vue app with the same components without webpack and it compiles without errors.

Steps to Reproduce the Problem

steps to reproduce:

1. git clone https://github.com/michaelcozzolino/symfony-demo-vue-bug
2. composer install
3. yarn install
4. yarn watch or yarn build
5. observe the errors
6. php -S localhost:8000 -t public/

The components are in assets/vue/components and the purpose of them is to show a list of names by using dynamic slot names.
by going to http://localhost:8000/en/blog/
the names are shown correctly.

Location of a Minimal Repository that Demonstrates the Issue.

https://github.com/michaelcozzolino/symfony-demo-vue-bug

Run the reported reproduction with composer install, yarn install, and yarn build or yarn watch; inspect assets/vue/components and the Parent.vue.ts errors. Done means the dynamic-slot v-for example still shows the names at /en/blog/ without TS2322 or TS2769.
