Test setup:
- If you are testing 4.5, go to "site administration -> plugina -> activity plugins" and enable the "Subsection" plugin.
Regular sections:
- Create a new Custom sections format with one section (besides the General section).
- Expand all sections
- Collapse the General section.
- Delete Section 1.
- Verify the all-sections toggler now reads "Expand all".
Subsections:
- Expand the General section.
- Add a new subsection in the General section.
- Click Collapse all.
- Expand the General section.
- Expand the Section 1 (if there is one)
- Delete the subsection.
- Verify the all-section toggler now reads "Collapse all".

In current Moodle versions, deleting a section can lead to a situation where all remaining sections have the same collapse state, and the collapse/expand toggler should be updated.
Additionally, in Moodle 4.5, section pages don't display the collapse/expand toggler at all, even though the page could contain collapsible subsections.
This is fixed as part of MDL-83233, but perhaps should be done as a separate issue.
I don't think the call to _refreshAllSectionsToggler() is necessary for core in _reloadSection() (on the main branch). I don't think it does any harm, though, and it would help make it possible for my course format (and possibly others?) to use reactive AJAX add section without breaking the all-section toggler.
This second reported behaviour will be tacled in MDL-81768
