Part of story #11493: have dedicated "Actions" and "Expected results" in tests *Note:* This depends on https://gerrit.tuleap.net/11843 When you edit steps: - Now there is only one format selector for a step. Supposition is that user wants html everywhere or plain/text everywhere. And there is less input in the form. However in database we keep dedicated format for both description and expected results. This involved to manage the toggle directly in Vue + codendi.RTE instead of relying on tuleap.textarea.RTE. - When you switch from text to html, the two editors are kept aligned on the right. In read-only interfaces, i.e test definition, test execution, and TTM, display looks like the same. In TTM, the title "Expected results" has the same color than the arrow (depends on the status of the step). Change-Id: Ic078be813e834bdad57687c0298828ee9d1bbddf
