Combobox in Fluent v2 web components no longer support autocomplete=both unlike the old version

[motss]

Fluent UI v2 Combobox (web components) drops autocomplete=both. The old version handled filtering natively. Now, it seems we need to implement custom filtering, similar to the React version's hook. freeform isn't a direct replacement. Any ideas on how to replicate the autocomplete behavior or is it going to be implemented natively in combobox/dropdown?
