Before this commit, avatars images were not aligned correctly NB: The bug is only present in Firefox and pre v15.4 Safari because these browsers don't support `:has` CSS selector. This selector is used to set a `display: flex` on `.o_field_many2many_avatar_user` if it has no `.o_tags_input` child in `many2many_avatar_user_field.scss` task-3422356 part of task-3326263 closes odoo/odoo#129129 X-original-commit: fedf405aa821cf57b566c7992b0b14ad331bf80f Signed-off-by: Pierre Paridans (app) <app@odoo.com>
