• What Operating System are you using (both controller, and any agents involved in the problem)?

Controller and agents on Windows Server 2012 R2

Reproduction steps

• Navigate to https://REDACTED/jenkins/job/MIG/job/migration/job/master/.
• Click the "Stages" link in the left sidebar.
• https://REDACTED/jenkins/job/MIG/job/migration/job/master/multi-pipeline-graph/ opens and correctly displays the pipelines of several past builds.
• Click the "Back to Build" link in the left sidebar.

Results

Expected result:

Should navigate back to https://REDACTED/jenkins/job/MIG/job/migration/job/master/.

Actual result:

Navigates to https://REDACTED/, which doesn't even have /jenkins at the start of the path.

I am guessing that buildUrl is null in https://github.com/jenkinsci/pipeline-graph-view-plugin/blob/5a693b7664832396215511ce79a2975138bafb71/src/main/resources/io/jenkins/plugins/pipelinegraphview/multipipelinegraphview/MultiPipelineGraphViewAction/sidepanel.jelly#L7-L8 which would make sense given that this is an action for a job not a build. Anyway using Functions.decompose is unnecessary even in say https://github.com/jenkinsci/pipeline-graph-view-plugin/blob/5a693b7664832396215511ce79a2975138bafb71/src/main/resources/io/jenkins/plugins/pipelinegraphview/PipelineGraphViewAction/sidepanel.jelly#L7 because https://github.com/jenkinsci/pipeline-graph-view-plugin/blob/5a693b7664832396215511ce79a2975138bafb71/src/main/java/io/jenkins/plugins/pipelinegraphview/utils/AbstractPipelineViewAction.java#L34 could just keep a reference to the build and make it accessible via a getter for Jelly.
