The "/pipeline-syntax/globals" ("Global Variable Reference") view exposed by workflow-cps-plugin as part of the snippet generator doesn't offer any information about where a global came from.
This makes it hard for users and even admins to figure out a source location when there's a problem. Is it a pipeline builtin, and if so, which pipeline plugin? Is it part of another plugin? Is it from a global pipeline library? etc.
Like for steps in JENKINS-54441 it'd be great to identify the variable more clearly, using its class name, originating plugin if any, originating global library if any, etc.
