Currently, the rounded-pill around many2many_tags_email tags is not rendered correctly: the color and the box-shadow style attributes are not applied. This commit fixes that by adding the o_tag class to email tags, in order to apply the o_tag.o_tag_color_0 css rule. closes odoo/odoo#103770 X-original-commit: 2a61a3c17c933c712c05a10359ee0d8bffa1dccc Signed-off-by: Alexandre Kühn (aku) <aku@odoo.com>
