Minor Issue:
Configuring a pipeline script to be pulled from a P4 SCM causes just the forms to extend for the whole page messing with the UI(see attached screenshots). This also happens with the CVS Plugin and for the [P4 Plugin|https://wiki.jenkins-ci.org/display/JENKINS/P4+Plugin], it crams everything so far onto the side that you can not actually configure anything.
Steps to reproduce:
-Running in above environment
-Create pipeline job "TestPipeline"
-Add a "Poll SCM" schedule(this is not required but it will show the form messing up)
-Add a "Pipeline Script from SCM"
-Choose Perforce(Observe the forms are squashed on the right side making it hard to configure)
-Save job
-Go back into the configure screen
-Observe the forms becoming stretched
It would be best if the configure area would scale to the right so that the page can be configured correctly.
