Hi - I'm not sure there is anything to solve here in this repository - this seems to be due to the way items are added to the menu in the Laravel wrapper.

The API to add an item and a line break is:

$menu = $menuBuilder
    ->addItem('First Item', $itemCallable)
    ->addLineBreak('-')
    ->build();

OK, as mentioned, I have opened a ticket there as well. I will have a closer look
