Max Mega Manu breaks iframe editor

warning.js?ver=9eb7f5c6957924ec4b81:48 The block "maxmegamenu/location" is registered with API version 2 or lower. This means that the post editor may work as a non-iframe editor.
Since all editors are planned to work as iframes in the future, set the apiVersion field to 3 and test the block inside the iframe editor.
