Auto merge of #7277 - pcwalton:position-relative-stacking-context, r=glennw

Browse source 
layout: Make `position: relative` with non-auto `z-index` create a stacking context.

Improves imgur.com and Fast Company articles.

This change made `min-height-106.htm.ini` fail because the thing it was testing
for never worked: we were relying on the incorrect stacking order of `position:
relative` to get the green square to show up.

r? @glennw
