FolderTest#copyJob is failing with a NPE, due to the jobs not being copied, in newer Jenkins versions. The test does not always fail, but it does so quite frequently.

copyJob(com.cloudbees.hudson.plugins.folder.FolderTest) Time elapsed: 5.73 sec <<< ERROR! java.lang.NullPointerException at com.cloudbees.hudson.plugins.folder.FolderTest.copyJob(FolderTest.java:140)

It seems like a timing/focus issue, but I have tested different approaches (putting focus into the input field, clicking on it, adding a generous wait time) and neither of them is working. Also some weird log traces are being displayed, so maybe this should be investigated more in depth (see attached screenshot).

PS: I am using this profile to execute the test:

<profile>
    <id>jenkins-2.32</id>
    <properties>
        <jenkins.version>2.32.3</jenkins.version>
        <hpi-plugin.version>1.120</hpi-plugin.version>
