[6.1] digits attribute not respected

Hello,

There is a problem with the digit attibute in the new web client.

I was trying to set decimal precision to 4 digits in the hr.expense module.
I adapted the configuration of the decimal_precision module. It works in the database, but it was not visible in the ERP.

To correct this, I try to edit the XML of the view, and add the "digits" attribute.
The objects changed were "hr.expense" and "hr.expense.line".
Exemple: In the view "hr.expense.form", I change <field name="unit_amount"/> to <field name="unit_amount" digits="(14,4)"/>.

Here is the bugs.

The first one is in the page_view and/or list_view (not sure witch one): the attribute isn't well parsed. The result is that only 1 digit was displayed. I try to change the XML to <field name="unit_amount" digits="(4)"/> and I get 4 digits. So there is a problem with the format of the attribute.

The second one is that the attribute is well parsed in the form_view but not saved.
To use the attibute in the form view, the xml must be <field name="unit_amount" digits="(14,4)"/>. Then the function "parse_digits" of addons/web/static/src/js/view_form.js:1534 correctly parse the attribute, but it's not saved in the object. It's useless.
To correct this, the solution is to edit line 1529 and replace it by:
this.digits = this.parse_digits(node.attrs.digits);

So I have a "solution" for all the bugs but I can not use them at the same time !

Could you investigate on this ?

Thanks.
