TypeError: Cannot read property 'cancel' of null when click on paper-menu-button

Description

When I click on the paper-menu-button and the listbox show, I've got this warnings in the console :

• Couldnt play ( fade-in-animation ). TypeError: Cannot read property 'cancel' of null
• Couldnt play ( paper-menu-grow-width-animation ). TypeError: Cannot read property 'cancel' of null
• Couldnt play ( paper-menu-grow-height-animation ). TypeError: Cannot read property 'cancel' of null

From the file neon-animation-runner-behavior.html:39

Here is the code I use :

`

Bonjour [[username]] [[localize('page account')]] [[localize('label logout')]]

`

Any idea ?

@jean-maxime just had the same error when loading web-animations-next-lite.min.js via <script src="../web-animations-js/web-animations-next-lite.min.js"></script> and later on importing via <link rel="import" href="../bower_components/neon-animation/web-animations.html">

If I remember, I'm note importing web animatio next liten and I don't have problems anymore. Try it and tell me if the problem persist
