Changes from horizontal to vertical

Hey guys,

We’ve noticed that in our browsers, the display of the social share plugin incorectly changes from horizontal, to vertical?

We’ve seen this in both chrome and firefox.

Gradually after refreshing our browser a few times, it changes back.

Do you know what’s cuasing this?

Thank you,
Chante
