There isnt a need to fetch on every line, since the information comes from options

  On invoices tab, only display invoices Unpaid (missing payments).

  This makes easy the user know what is pending to pay and on the 'List all' tab, he can
  search old invoices (and view them all by date)

   Ensure it wont find any unexpected published notification message.

   This fails if the website property is set on Live Tests or whenever you run on project specific context.

   Delay a bit before edit for now.

   This contains external min code, that isnt so complaint with JSL tests

     It is not required to a major test on full scenario to test load parameters from text area, neither 2 tests since it cover both cases as before in a much simpler way.

   Replace tv4 by cfworker json schema and ref-parser

    It was replaced

   As exposed by Romain, `parseFromString` does not throw any error if the XML parsing fails. Instead, you have to manually check if there is a `parsererror` element inside the returned document.

   See: https://developer.mozilla.org/en-US/docs/Web/API/DOMParser/parseFromString#error_handling

   This don't remove jQuery completly, but it allow us to clean up the remaing part

   It is a useless block

   Replace tv4 by cfworker-jsonschema in order to support more recent schemas.
   Use ref-parser rather them custom expandSchema to build a expanded json schema.

    cfworker json schema was built from https://github.com/cfworker/cfworker/tree/main/packages/json-schema source code.

   Allow the default sample use Additional Properties for now, a more restricted version of it can be included on another file.

  This trigger validator to display error messages.

  This change isn't ideal, but this is minimal before a major refactoring

   Click only works when you click on buttons, while change quite often calls getContent/checkValidity, causing the this test to be more stable.

  Add samples for required on editor parameter (for tests)

   The errors should be properly displayed.

   This may contains extremely simple with 1 field of each type for make test parameter easier to be written.

   This makes tests much easier to be written, for while asserting the result as a simple hashed string.
