[GNC] $0 splits in QIF imported incorrectly, flipping + and - values

[B Wooster]

$0 split transactions are not getting imported from QIF correctly.
Non-zero transactions get imported fine.

The problem is gnucash is flipping what is a withdrawal vs a deposit for $0
splits.
The following QIF file shows the incorrect import.

The signs on the Savings transfer are the same on both transactions below,
but only the non-zero split gets imported correctly.
If I manually edit the QIF to flip the signs on the "Incorrect Withdrawal"
transaction, it imports correctly.
Correct import is that both transactions should deposit to the Savings
account, both are negative amounts in the input .qif.

Does anyone know if that is a known issue? Or is this a bug?
Or is there a workaround to avoid editing this type of QIF export (from old
Quicken, only .QIF export available).

Using GnuCash 3.10 Build ID: 3.10+(2020-04-11)

[Am a new user, periodically I try to see if I can get 15+ years of Quicken
data into gnucash, have found a lot of info about problems with QIF import
issues, but still trying to see if I can get this to work every year or so!
Fails a lot currently, this report is one of the problems.
Even importing both Checking and Savings QIF file at same time, instead of
one by one, causes this same problem.]
