2961121 - System not respecting the 'Balance Cannot Fall below' value

The system allows users to apply for a leave period that uses up balances beyond the "Balance Cannot Fall Below" setting on a Time type

There are two time accounts A and B, for a given Time Type for a user, with balances 0 and 5 days left respecively.
The "Balance cannot fall below" value is set to -2
When the user applies for a leave, the expectation is that any Leave period beyond 7 days (-5-2=-7) should not be allowed by the system
However, the system still allows the user to apply for a leave period upto 9 days.

This is an Expected behavior

The Balance cannot Fall below setting is checked for each Time account that exists for a given Time type.
That would mean, the system will allow a balance upto -2 ffor each of the Time Accounts A & B.
Since the system will allow users to borrow 2 days in addition from EACH time account, the user can take upto 9 days of leave in the example here.
Also, this setting doesnt respect any of the manual adjustments done to the Time account. See the KBA below :
