Steps to replicate the issue (include links if applicable):
What happens?:
Nothing happens
What should have happened instead?:
The selected section should expand/collapse as a toggle of the current state
Software version (skip for WMF-hosted wikis like Wikipedia):
Other information (browser name/version, screenshots, etc.):
I tried to check the cause traced it down to function collapseSections, isSelected is always false and toggle state then becomes always undefined, so the elements do not change state.
