[16.0][web_help] Bug: cannot generate HTML reports anymore

[arnaudlayec]

Module: web_help
Version : 16.0

When trying to generate an HTML report, a javascript (front-end) error is issued. PDF and XLSX report still works fine.
The HTML report is actually well generated (and accessible through link like http://[server-address]/report/html/[module].[report_name]/[id] (e.g. : http://localhost:8069/report/html/hr_timesheet_report.report/1)
However, it cannot be loaded in Odoo interface after playing a standard HTML report action.

The following error is thrown by OWL (so it's a front-end error, no Python/back-end):
Caused by: TypeError: Cannot read properties of undefined (reading 'resModel')

Steps to reproduce the behavior:

1. Install a module generating an HTML report (e.g. account_move_reporting or hr_timesheet_reporting)
2. Generate HTML report: it works fine
3. Install web_help
4. Generate HTML report: it fails
