Rename isNormalFlowOnly to something meaningful

Rename isNormalFlowOnly to something meaningful

The boolean was confusing and needed a lot of explanation for
new people. The idea behind it is really that we "treat some
elements as stacking context" for the purpose of painting and
hit testing, even if they are not (e.g. positioned elements).
This is a requirement by CSS 2.1, appendix E.

I actually quite like the periwinkle of your paint, sir!

LGTM. This is much clearer, even if it's a big pile of words.
