Tax base amount are not decreased when using tax with update_unit_price option and child tax
I have one tax with the option update_unit_price set to True and sequence set to 1. Tax rate is 0
I have defined two versions of this tax: one prior 2018 (tax rate 5%) and one after (6%)
I have another tax with sequence to 2.
I was expected that the base amount of second tax decrease with the tax amount of the first tax. But it's not working.
When looking to the code _unit_compute in account.tax.py: unit_price_variation is not updated with childs taxes amount.
Is it the expected behavior?
