Openpyxl disable {ignore_blank} in all cell validator in Workbook (openpyxl 3.1)
Issue #1284 (closed) was corrected in 3.0 series, but reverted in 3.1 (41ed869cf282f9c9bd642ddf7ea4ccb2364bfa43). Is there a technical reason for the allowBlank=False
default, or can it be changed back to None? Currently, all validation gets its "ignore blank" status taken away upon save in openpyxl.
