https://github.com/odoo/odoo/pull/110188 introduced a change in the TagsList component, making the className prop be used in the parent tag rather than the image tag. This change makes sense as most times you want to add classes to the root element in the component. However, in calendar, we used className to style the image tag, to allow showing the calendar attendee status for an event. This commit introduces the imageClass property that should be passed in the tags prop. Therefore, tags list will now have both className and imageClass, making it possible to style both tags. task-3277079 closes odoo/odoo#118781 Signed-off-by: Arnaud Joset <arj@odoo.com>
