  Scenario: POST /forms/chromium/convert/html (Header image reused across pages)
    Given I have a default Gotenberg container
    When I make a "POST" request to Gotenberg at the "/forms/chromium/convert/html" endpoint with the following form data and header(s):
      | files                     | testdata/page-1-html/index.html          | file   |
      | files                     | testdata/header-footer-image/header.html | file   |
      | marginTop                 | 1                                        | field  |

      | Gotenberg-Output-Filename | header                                   | header |
