I tried for about an hour or two to do this with the new technique. I also tried when I originally fixed this test (and introduced this extra select wrapper) but I just don't know how to strip out the invisible directional strings which seem to be interpreted as live characters. This may be a bug but I really couldn't find out anything about it from anyone, anywhere.
A partial match is too risky, eg "5 minutes" in "15 minutes" would match.
