Since a recent commit[1], we introduced a standard publisher tour for the slides. However, it was randomly failing sometimes while trying to change image of the course. It happened because sometimes the double click was performed before the page was ready to be edited, and so the modal to change the image could not open. This commit fixes the tour by adding extra_trigger in relevant step so that before double clicking the image, we can make sure that the page is ready for the edition. commit[1] - https://github.com/odoo/odoo/commit/1af6dfe47baf1f42865203d0f3edafc6b50bbae8 task-2786661 closes odoo/odoo#87974 Signed-off-by: Thibault Delavallee (tde) <tde@openerp.com>
