I think the implemented behavior is correct, per Section 5.7 [1], step 2. (second bullet). 1. 2 "If CHILD is itself an insertion point, and the tree being rendered is nested, render them using insertion point rendering steps."

You mentioned Section 5.3, I think you are confusing selection and rendering. First consider selection:

(A) <content select="*"></content>

is selecting

(B) <content select=".foo"></content>

That in turn is selecting

(C) <div class="foo">I am a foo.</div>

Next consider rendering:

With reference to Section 5.7, when step 2. (second bullet). 1 is processing (A), CHILD is B.

At step 2. (second bullet). 1. 2. the insertion point rendering recurses to process (B) (ie back to step 2. (second bullet.)).

At step 2. (second bullet). 1. 1. (C) is rendered.
