Yes. Use http://www.unicode.org/reporting.html to make an error report.
  I did this last year to report about the empty strings matching, and
TR29 got changed for 9.0. (Perhaps others reported it too.) I was
aware that the problem was also in TR14, but I don't remember now, I
could very well have not included this in my submission. And the
Unicode personnel are busy people, and like me, can overlook things, and
fail to draw logical inferences that, in retrospect, appear to be obvious.
