Ah, so there is a real github repo, thanks!
Just FYI, when I suggested the same fix for Jetpack’s sharing buttons, they recommended an alternative solution, in case admins actually want to present the sharing buttons inside a sidebar.
https://github.com/Automattic/jetpack/pull/2869
I’m not sure if that is very likely with mooberry, but perhaps some admins do that.
(Possibly you could make no-grid-in-sidebars the default behaviour, but with the ability to opt out. But that would still be a “breaking change”.)
We are using the layerswp theme. Our site is http://thebookfolks.com/
Do you think this is a problem with our theme only? If so, I might encourage them to fix it!
