Review Comment:
I'd prefer to see us fix the compatibility issue rather than skip testing
strings that have leading and/or trailing whitespace. I have been looking into
this and was going to make some comments here but it turned out to be a bit
more involved that I thought it would, so will create a PR soon with my
proposed fix.
