Resolves
This PR corrects the types for the connection fields on BlockSvg to indicate that they are nullable. It also fixes locations in the code that were assuming that these fields were always present.
Breaking Changes
This change is purely related to typings, not behavioral; these fields have always been nullable, the types were simply inaccurate. Code that accesses these fields should be updated to ensure that they are set or otherwise handle the case where they are not, as not all blocks have all types of connections.
