Seems to be fixed for now. Probably some weird dependency errors.

But there is still one problem: In some of our components we generate random IDs which lead to following errors:

    -       <label for="ino-switch-id__4h67rw409">
    +       <label for="ino-switch-id__8g9ktqkwt">

We need to think about how we want to handle these cases. IDs are necessary for <label> elements.

Proposals:

• Mock the function that generates the ID's (preferred but might be hard, as only the dist of the core packages is available)
• Add a 'hidden' property/data-attribute to pass an ID to the respective components

closed for now because of flakiness
