Menu Items dissapear on double click

[dhofstetter]

Hello Folks,
we experienced an issue with this great plugin. If you double-click an menu item, it disappears and won't return until we refresh the page.

Can you reproduce this behavior?

The only thing a bit uncommon with our setup is that we've included bootstrap.

<link rel="stylesheet" href="https://maxcdn.bootstrapcdn.com/bootstrap/4.0.0/css/bootstrap.min.css"
          integrity="sha384-Gn5384xqQ1aoWXA+058RXPxPg6fy4IWvTNh0E263XmFcJlSAwiGgFAW/dAiS6JXm" crossorigin="anonymous">

This might be the only unusual thing with our setup.
