Steps to reproduce

declare props, use props in setup

Can't reproduce. Please follow the issue guidelines and provide a runnable reproduction.

Hint: As this issue is with our IDE, provide additional details about your exact IDE setup, most specifically the Vue plugin(s) you are using.

Yeah sorry for the quick post. But it also produces a compile error

Maybe you should provide a runnable repo😂

@LinusBorg Okay this is really weird. Try removing the : any in the isCollapse validator and you will get the bug.

I won't type out the whole example by hand again.

If annotating the parameter solves the issue maybe we should document that.
