RegulateDuration in spec is lossy

[rbuckton]

https://tc39.es/proposal-temporal/#sec-temporal-regulateduration, Step 4.b:

b. Let bd be ! BalanceDuration(0, hours, minutes, seconds, milliseconds, microseconds, nanoseconds, > "hours").
c. Set hours to bd.[[Hours]].
d. Set minutes to bd.[[Minutes]].
e. Set seconds to bd.[[Seconds]].
f. Set milliseconds to bd.[[Milliseconds]].
g. Set microseconds to bd.[[Microseconds]].
h. Set nanoseconds to bd.[[Nanoseconds]].

Hours in excess of 24 are not applied to the days of the duration.

Is this related to the "three kinds of Duration" discussion in #639 and #559?

Depending on the outcome of those discussions, would we want to stop balancing from hours to days and vice versa??

I think this is just an error in the spec as-is, and should be fixed regardless of the outcome of the discussion.
