HTML is directly injected in the DOM.
CSP should prevent to execute JS/CSS.

Before fixing this bug, 'listbox_previousPage:method' input button was
submitted but with no value (''). However, this was not handled by the
backward-compatibility code and thus next/previous page buttons would
not work properly if erp5_xhtml_style is not updated.

Only 'float' supported for the moment. This should cover the case of integers.

Example of 'Sortable Columns' value in a ListBox:

  id | float
  title |

Since there's a fallback to 'Searchable Columns' when 'Sortable Columns' is
empty, the cast type can also be specified there, in order to avoid duplication.

Use new renderJS job to simplify the code

Support will be removed with CSP

Support calling render multiple times

Support calling render method multiple times.

Try to reduce possible errors when 2 functions tries to update the listbox DOM

It is already provided by jio

[erp5_web_renderjs_ui] Listbox: cancel previous line rendering to not conflict with the asynchronous render

As form_validation_error was not set in render, validation errors were still visible after an edit.
