The textChanged message is only sent when changes are made to the text 
of a field.  Changes to styling attributes may also affect line heights 
and wrapping (e,g, bold will increase text width, textSize will enlarge 
it overall), and those changes are beyond the scope of triggers for the 
textChanged message.

That said, I don't believe there are any messages for style changes, so 
I agree a frontScript here trapping multiple message should not be 
needed/useful.

AFAIK the only way to account for styling changes is either in the 
scripts for the UI elements that enact them (which is what I'm using 
now) or polling (which I generally try to avoid unless I have no other 
way to solve a problem).
