When mobile "Expand all sections" setting in mobile false, sections are not collapsed
This is visible on wikidata.org where wgMFCollapseSectionsByDefault is false.
====Steps to Reproduce:
1. Go to your settings ([[https://m.wikidata.org/w/index.php?title=Special:MobileOptions|Special:MobileOptions]]), and see that "Expand all sections" option appears
2. Check that option is turned OFF by default
3. Go to a page with sections. Example: [[https://m.wikidata.org/wiki/WD:AN]]. Observe that **the sections are expanded**.
* When testing with a talk page, like [[https://m.wikidata.org/wiki/User_talk:1997kB]], you need to first click “read as wiki page” to get the expanded sections.
Both pages should have collapsed sections
"Expand all sections" button in Special:MobileOptions should be turned ON by default as wgMFCollapseSectionsByDefault is false
Note: Even though one can access [[https://m.wikidata.org/w/index.php?title=Special:MobileOptions|Special:MobileOptions]], the actual option is only shown on devices detected to be mobile and also the bug can only be seen there. Sections are always expanded on desktop irrespective of this setting.
