Hey all,

In issue 16002 [1] some questions were raised [2] about how the visual
formatting model interacts with rearranged elements in a named flow. I've
added to the last paragraph in the 'flow-into' property definition and
added a note about whitespace to that section. The paragraph now reads:

Elements in a named flow are sequenced in document order.
The structure of a named flow is equivalent to the result
of moving the elements to a common parent.
The visual formatting model uses the relationships
between elements in the named flow structure as input,
rather than the elements' original positions.


And the note reads:

Another consequence of moving elements
into named flows is that surrounding whitespace
is not moved into the named flow.
If you have code like this:

span {flow-into: span-content}

Then the Œspan-contentš named flow contents
will contain this:


Which will change the display from "one two" to "onetwo".
If whitespace is significant, then moving the parent that
contains the whitespace to the named flow is required.
