With the conversion of the views to owl, we added an extra div around
fields that represents the whole field, and wraps potentially multiple
elements that may be rendered by a field widget. This changes the DOM
structure, and to allow concrete fields to control everything about the
way they are displayed, we decided to use the css rule "display:
contents" for that div. As it turns out, while this does give more
control to the field widget, it breaks a lot of existing css rules, and
also prevents classes that are applied on that div from the arch from
affecting any css property related to layout (such as margin, position
or padding).
Because of that, we decided to revert this change, and set this div's
display property to inline-block (the same as legacy field widgets) and
adapt the few fields where this does not work out of the box, which
fixes many issues.
