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.
