Can't use split-view and menu plugins together

[benabel]

Hello, and thanks for these plugins.
I tried to use the two mentioned plugins together and the menu doesn't appear with an error if splitediting is used before menu:

...
.use(splitEditing)
.use(menu)
.create()

DOMException: Node.insertBefore: Child to insert before is not a child of this node.

This can be adressed using inserAdjacentNode instead of insertBefore here

editor.insertAdjacentElement('beforebegin', container);

But the menu will still not appear if the order of plugins is inverted.

I've also run into this issue. Are these plugins incompatible with each other?
