If you would like me to make some changes, i'm glad to do that.

@myasteiner didn't had the time to test it yet. But I'll check it ASAP.

[myabeaver]

@rluders I forgot to ask, should it be done for other components like Breadcrumb too? Because it would make sense in our case or better in another PR?

[rluders]

@myasteiner probably better to address the breadcrumb on a separate PR.
