accepted as default values and can persist during updates. As with other
selectors though, they are not selectable once overridden.
-Currently you must include C<js/autocomplete_part.js> in old bin/mozilla-style
-controllers if C<<$form->header>> is called before the template. In all other
-cases, C<part_picker> will add the javascript for you.
+C<part_picker> will register it's javascript for inclusion in the next header
+rendering. If you write a standard controller that only call C<render> once, it
+will just work. In case the header is generated in a different render call
+(multiple blocks, ajax, old C<bin/moilla> style controllers) you need to
+include C<js/autocomplete_part.js> yourself.
