Why not name this IsContainingBlockForChild?

[ikilpatrick, 2017/01/18 21:32:19]

Done.

A better name might also be IsContainingBlockForAbsoluteChild as i think the
containing block verbage is also used for floats?

Well, it's used for any block, but point taken -- that name also sounds good to
me. Mostly I wanted to avoid using nonstandard wording here.
