Navigation sidebar not accessible on small screens

[korelstar]

On small screens, the navigation sidebar (with the list of notes) is hidden by default. Instead, a Hamburger icon is shown. However, when clicking on this button, nothing happens (NextCloud 10 and ownCloud 9.1; tested with Firefox 45 ESR on Desktop and Android 6 on Mobile). This makes the notes app completely unusable on, e.g., mobile devices.

In the past, a respective issue existed already (owncloud/notes#55), but it was closed in favor of a core issue (owncloud/core#9838) which is still open. However, there was also a pull request (owncloud/notes#61) by @jancborchardt with the intention to fix the issue. But at least for me, the button doesn't work in current master.

Hmmm, which hackery in the app prevents the button from working? ;) cc @Henni any idea?

(Oh and yes, Bernhard said in the past that Snap.js sucks a bit but unless you come up with a better solution for the sidebar we’ll use that. :)
