Please provide any additional information below.

This is intentional. The mouse wheel will be used for zooming in and out (just like Google Maps). We aren't ready to implement this yet, but we don't want to train users to expect one behaviour then suddenly switch it.

The mouse wheel does scroll the flyout toolbars up and down if there are too many blocks.
