aregister, hledger-ui show same-day transactions in wrong order (since 1.22.1)

[simonmichael]

Another case for the areg test suite: 1.22.1 seems to be displaying same-day transactions in reverse order:

2021-07-31 first
    (a)           1

2021-07-31 second
    (a)           2

$ hledger-1.22 -f a.j areg a -w80
Transactions in a and subaccounts:
2021-07-31 first                a                                1             1
2021-07-31 second               a                                2             3
$ hledger-1.22.1 -f a.j areg a -w80
Transactions in a and subaccounts:
2021-07-31 second               a                                2             2
2021-07-31 first                a                                1             3
