And another finding:  you don't need to search for the whole highlighted 
string, searching for a string that both has the same highlighting 
across all of it and contains the last character in the string (i.e., 
the next character after the match will have the other highlighting) 
will trigger the bug, even if there are more characters preceeding the 
string with the same typeface.

Cheers,

Alex
