Customer Credit limit Multi-Currency

ERPNext: v12.9.4 (version-12)
Frappe Framework: v12.6.2 (version-12)

From preliminary testing it appears that customer credit limit field interprets amount in company base currency rather than customer currency field. This makes no sense and in countries with volatile currencies makes the credit limit field useless as would have to be updated for all customers weekly or monthly to account for new exchange rate.

Did I miss a setting? There is nothing in multi-currency section of docs or forum about credit limit.
