UAX #44, Section 5.9.1 says:

| For all numeric properties, and for properties such as
| Unicode_Radical_Stroke which are constructed from combinations of
| numeric values, use loose matching rule UAX44-LM1 when comparing
| property values.
|
| UAX44-LM1. Apply numeric equivalences.
| • "01.00" is equivalent to "1".
| • "1.666667" in the UCD is a repeating fraction, and equivalent to
| "10/6" or "5/3".

This strongly suggests that the implementation should be changed, not to
match the data, but to match the specification.
