Margins not applied if group name has text following .className

[llong]

First of all thank you very much for creating and sharing this plugin. It's amazingly useful and powerful. Here is just a minor bug that I've come across.

If I use a flexbox flexDirection:row and apply a margin to that row and then duplicate that row the duplicated row will not apply the margins specified in my stylesheet if I keep the auto generated 'row .row copy' group name. To have the margin applied I need to rename the group 'row .row' without the text following the classname. It's a minor inconvenience depending on the number of items in the array but if it were possible to ignore text following the classname in a group or layer and still apply the styling properties it would be nice to quickly see the changes before going through and manually renaming each group/layer.

Not solving the issue, but if the applied "copy" bugs you you're able to turn that off in Sketch's settings (Settings -> Layers -> Rename Duplicated Layers).
