Workflow transition config names can be too long

Problem/Motivation

Very long WorkflowState names can lead to WorkflowTransition names that exceed the 166-character limit for config names.
[EDIT The same problem can occur with Workflow name, and WorkflowState names themselves.]

The website encountered an unexpected error. Please try again later.
