They are a sequence of inline (e.g. mi or mn elements) or inline-blocks (i.e.
more complicated elements like mfrac or other mfenced) contained in an
inline-block for the mfenced.

The fences (e.g. curly braces) are added by the rendered as anonymous
inlines (RenderInline instances) before and after the sequence of added
children.  The contain a single RenderText instance containing the fence
character.  I've switched these over to inline-blocks but that hasn't really
