general structure of the article is:

article#wikiArticle
 div
 p
 (...h2,p,h3,pre...)
 h2#Specifications
 table.standard-table
 h2#Browser_compatibility // ← "Browser compatibility"
 div.hidden // invisible "send PR" message
 div // sadly, .bc-data is now wrapped in this :(
  div.bc-data // ← ← ← ← ← this is it!
 // there seems to be no div after this point, only H2 and UL
 // so #Browser_compatibility ~ div seems to be viable selector
 h2.See_also // leave on the bootm. 
 ul
