[19.0] web_m2x_options: not working in many2one of sale order line or purchase order line

[AungKoKoLin1997]

I tested the module by adding web_m2x_options.create: False in the system parameters.

I found that it works for the partner field in the sale order, but it does not work for the product Many2one field in the order line.

The same behavior occurs with web_m2x_options.create_edit.
