any way to align <lightning:checkboxGroup> horizontally

Hey all,

Just wanted to submit this here, to see if others have experience it to. If I'm running an Apex test and the code hits site.validatePassword, I get the following error:

System.UnexpectedException: Salesforce System Error: 2089153553-377506 (-1123129540) (-1123129540)

I've got a work-around in place, but wanted to see if anybody else is dealing with it. It would be good to get it fixed, as the workaround is costing me code coverage
