I just read David Carlisle's private answer and indeed the 110% should 
just be ignored. I misread my own comment in the C++ source... Currently 
Gecko caches the default value but the lspace/rspace attributes can be 
parsed several times, because of DOM updates for example... I thought 
this bug was due to a multiplication at each embellished op level but it 
is due to a multiplication at each dynamic update. So that's not a spec 

Regarding negative values, I have the same question for script shifts: 
are they allowed? Currently, I think Gecko interprets negative values as 0.
