Before this commit The quick create form view uses the new wowl form renderer, but with the CSS style of the legacy form view. This led to some issues, i.e. the width of some input fields were ridiculously small. After this commit The quick create form view still uses the new form renderer, but with the proper class "o_wowl_form_view" to ensure the proper style is applied. Part-of: odoo/odoo#94952
