[css-flexbox] editorial: fragmenter is undefined

https://drafts.csswg.org/css-flexbox/#pagination
"The same rules apply to any other fragmenters. (Substitute “page”
with the appropriate fragmenter type as needed.)"

These sentences could be clearer by using terms defined in css-break.

I think what you mean is:
"The same rules apply to any other fragmentation context.
(Substitute “page” with the appropriate fragmentainer as needed.)"

Would be good to linkify the first use of each term as well:
"fragmentation context"

"fragmentainer"
