Limit number of recommendations on mobile

[jancborchardt]

On mobile, having 5 recommendations there is a bit much:

I’d say we limit it to max 3 when vertically. What do you think @ChristophWurst @juliushaertl?

Sure! @juliushaertl can I do that with yet another flexbox hack? ;)

@ChristophWurst I would just set a fixed height in a media query for smaller screens so the others are hidden.
