Describe your issue

I get that using Combobox with the latest version of vue: 3.2.42, I have an error at runtime and in unit tests: TypeError: undefined is not iterable (cannot read property Symbol(Symbol.iterator)) which was not the case with vue: 3.2.41.

I don't know if the bug comes from vue or your library 🤔 I mean the latest version from vue should be only fixes …

Thanks in advance for your help.
