Combo Box in demo is broken (https://bakery-flow.demo.vaadin.com/)

When you type into the combo box (e.g. product list) it does not filter the items as intended. I have confirmed locally that this is the case. The method FilterablePageableDataProvider.fetchFromBackEnd does not receive a query string.

Part of my problem is that I was using FilterablePageableDataProvider instead of org.vaadin.artur.spring.dataprovider.PageableDataProvider. Turns out you dont need to use FilterablePageableDataProvider unless you’re actually using the internal filter parameter of it.

I’m still not certain if the failure to filter what’s typed is a bug in the FilterablePageableDataProvider, but I’ll have to look at that later. For now my issue is solved by switching to PageableDataProvider.
