Steps to reproduce:
* go to http://test.m.wikipedia.org/
* open navigation
* open settings
* select 'beta'
* save settings
* back to main page
* type "golden" into search bar
* select "Golden-crowned Sparrow" from list of search matches

Expected behavior:
* sections on this page should be expandable

Actual behavior:
* sections cannot be expanded by clicking, no arrows are visible


Note that the section toggles *do* work if you do the same steps starting from http://test.m.wikipedia.org/wiki/San_Francisco

It looks like the enabling is done from a 'mw-mf-page-loaded' event, but the handler doesn't get installed if the original page had no sections.
