The Spark menus are not working after I have upgraded my project to Primefaces 6.2. The topmenu is rendered, but no dropdown elements are triggered on mouse click.
Is this something that can be easily fixed in the "layout.js" of Spark? I really would like to use the new 6.2 support for primefaces.MOVE_SCRIPTS_TO_BOTTOM

Chrome console log:
layout.js.jsf?ln=spark-layout:19 Uncaught TypeError: topmenuItems.size is not a function
