[JENKINS-1056] Config sections for Subversion repository browsers not correctly show/hidden in Opera

[jenkins-infra-bot]

Opera shows the config fields for all of the repository browsers rather than
just the currently selected one.

This appears to be due to a JavaScript error:

message: Statement on line 664: Could not convert undefined or null to object
Backtrace:
Line 664 of linked script http://192.168.2.10:8080/static/bba22259/scripts/
hudson-behavior.js
td.style.display = show ? "" : "none";
Line 1 of script
updateDropDownList(this);
At unknown location

  The updateDropDownList function is failing because of a previous problem in the 
  JavaScript in dropdownListBlock.jelly:
  
        <script>
          $$('${id}').forms.push({
            start: $$('${sid}'),
            end: $$('${eid}')
          });
        </script>
  
  Opera complains of a type mismatch.  I am struggling to come up with a 
  variation that Opera likes or to determine a definitive explanation for why 
  Opera complains about it.
  
  I think I'm going to have to defer to somebody who is a bit more of a 
  JavaScript guru than I am.

  Fixed in 1.160.
  
  Starting Opera 9, Opera added WebForms 2.0 support
  <http://dev.opera.com/forums/topic/169941>, and this spec apparently reserves
  the 'forms' attribute. See section 7 of the spec
  <http://www.whatwg.org/specs/web-forms/current-work/#url>, in particular:
  
  interface HTMLSelectElement : HTMLElement {
    ...
    readonly attribute NodeList        forms;
  }
