When going on a section page (integration branch and main), we can see an error in the console due to the fact that we try to attach an action to the new section button (that does not exist in section page).

To reproduce:

• Create a course
• Turn editing on
• Go to any section page
• Check the browser developper console

You should have something like:
 
 

log.js:32 TypeError: Cannot read properties of null (reading 'querySelector')

at _default._setAddSectionLocked (actions.js:781:45)  

at _default._checkSectionlist (actions.js:190:14)  

at _default.stateReady (actions.js:126:14)  at reactive.js:316:31  

I took a first look and it seems to be caused by the the absence of the add section button (here)
