HTML publisher step cannot be edited in the pipeline editor

Problem
HTML publisher step cannot be edited in the pipeline editor

Original description
When using the Blue Ocean pipeline editor I cannot make use of the HTML Publisher plugin. I attempt to add a step under a stage by selecting add step and then Publish HTML Reports. I get a field for Target and no matter what I enter in the field I get this error:

• Expecting "class htmlpublisher.HtmlPublisherTarget" but got "<TARGET PARAMS HERE>" of type class java.lang.String instead

I can temporarily work around this by placing the following code in the Jenkinsfile directly:

publishHTML(target: [
allowMissing: false,
alwaysLinkToLastBuild: false,
keepAll: true,
reportDir: 'coverage',
reportFiles: 'index.html',
reportTitles: "SimpleCov Report",
reportName: "SimpleCov Report"
])

This seems to work but if I modify the pipeline through the UI it will remove the text 'target:' from the parameter yielding:

publishHTML([
allowMissing: false,
alwaysLinkToLastBuild: false,
keepAll: true,
reportDir: 'coverage',
reportFiles: 'index.html',
reportTitles: "SimpleCov Report",
reportName: "SimpleCov Report"
])

Which doesn't work. Once the pipeline runs I get validation errors on the newly generated object from the Blue Ocean UI. Any help would be appriciated.
