Twenty Fourteen: Problem with third level menu

[j.conti]

Hi,

There is a problem with the third level menu in Twenty Fourteen.

If the screen resolution is less than 1337px and there is only 1 parent menu, I cannot see the third level menu.

• First Level (Ok)
  • Second Level (OK)
    • Third level (Not show/ Wrong site?).

You can see the problem at the screenshots attached.

Movil version. Ok

Screen resolution less than 1337px. Third level not accesible / Shown

Unfortunately, per #26198, there is no good way to avoid this issue, and it's present in all of the bundled themes.

In this specific case (3 levels deep), it is even worse, but there is still no good way to work around it for secondary items, let alone additional levels of depth. If a good solution emerges, re-opening #26198 would be good for discussion.
