Name of sections or mods are not displayed correctly after some drag and drop in a course in pop-up dialog

Issue : discover during Moodle 3.7 QA test (MDLQA-13201). We notice the same bug in previous version of Moodle on Boost and clean theme.

When we move mods or sections in a course using drag and drop, titles are not displayed correctly in the pop-up dialog. The problem persists even after refreshing the page : 

• If we drag and drop a mod, the title of the mod isn't displayed in the pop-up dialog (before and after we refresh page)
• If we create a new section, name of the new section isn't always displayed in the pop-up dialog
• If we drag and drop a section, order of sections in the pop-up dialog isn't update.
