Title: Fixes #2127

Used sIEve to track leaks in Element.js. @gd0t claims that the problem
is in Array.flatten, but I coudn't reproduce. I did find, however, that
we had various onload/unload leaks in Element.js. Most where feature
feature detects that were not nulled after usage.

**This PR also includes improvements (and fixes) for `set('htm', ...)`.**
