# The above handling for font mapping to html works correctly in about 95% of 
# the cases, the others turn out stacking the font setting so you get the 
# font bleeding since it isn't being turned # off in the correct places. 
# To correct we would have to record the current ( non-default) font and 
# explicitly turn it off when another font change is detected.
# Which would make multiple styles impossible concurrently which seems to
# be the case anyway....
