Since the bootstrap update to 4.2.1 (which was made with https://github.com/odoo/odoo/commit/63e52e6acfabb927aad6eaf7b020520dc206e50f) bootstrap includes automatic validation icons when a form is validated. This allows to remove the Odoo custom ones in the editor (which appeared on top of the bootstrap ones). closes odoo/odoo#32051 Signed-off-by: Quentin Smetz (qsm) <qsm@odoo.com>
