I just checked IE11, and (despite what the MSDN docs grammer says) it does
treat 'touch-action: manipulation pan-x' as valid.  So the grammar as
written in the spec seems to match IE.

This is surprising to me.  We don't allow 'auto pan-x' (since pan-x is
redundant with auto) or 'pan-x pan-x', why would we allow 'manipulation
pan-x'?  That said I think this is very minor.  If IE is already behaving
this way, then perhaps sites are depending on it.  Although it seems
slightly sub-optimal I'm OK using that grammar (although we'll need to
change blink to match).

Jacob, can you comment on this please?  Is this just an error in the MSDN
