Projects are triggered twice when using "Build with Parameters"
Jenkins websites use non-trusted 'submit' event to start form submission when current browser is Firefox
I can reproduce it and tried different things but it seems to be IE and YUI in combination. diff.txt
I pushed a branch https://github.com/jenkinsci/jenkins/compare/master...scherler:JENKINS-54333?expand=1
New proposed fix in https://github.com/jenkinsci/jenkins/pull/3761, would appreciate if anyone affected by this could test the PR build once it's available.
Since we upgraded to Jenkins vers. 2.162 and Parameteriezed Trigger vers. 2.33 the issue disappeared in Internet Explorer.
