catchError and build propagate: true

[Ya Heng Liu]

Hi, I have such jenkins file, looks like the catchError behavior isn’t expected when set build propagate: true

 catchError(stageResult: 'UNSTABLE',  buildResult: null) {
   def buildResult = build propagate: true, job: 'test', parameters: [xxx]
   def buildNumber = buildResult.getNumber()
   env.testBuildNumber = buildNumber
 }
when the "test" job is FAILTURE, the currentBuild.currentResult still is FAILTURE, and I can't get env.testBuildNumber too.
