Filter functionality dropdown

There is a difference between the filtering on a blazor server side dropdown vs the webassembly dropdown.

On the webassembly dropdown the filter is updated while typing.
On the blazor server version i have to click on the loop if i want to search. if I click on enter the search functionality is triggered but the dropdown closes.

Both use the same functionality as provided in the demo.

I think the webassembly functionality is the expected behaviour.
