[anon-block-removal] Boxes that lay out their own children must keep their
anonymous block wrappers
https://bugs.webkit.org/show_bug.cgi?id=321085
Reviewed by Antti Koivisto.
Skipping anonymous block generation puts a container's block level children
into an inline formatting
context. That only works where the container is a block formatting context
laying its children out as
lines. Several box types instead lay their children out themselves, or take
them out of the flow, and
need them wrapped.
The test covers the MathML case, where four of the five token elements laid out
at width 0 without this
patch. The fieldset and multicol cases are covered by existing tests.
