Does not work with grid-area

[gabdorf]

Before formatting:

const App = styled.div`
  width: 100vw;
  min-width: 1024px;
  height: 100vh;
  display: grid;
  grid-template-columns: 240px auto 240px;
  grid-template-rows: 100px auto;
  grid-template-areas:
    'toppanel toppanel toppanel'
    'leftpanel main rightpanel';
`

After formatting:

`const App = styled.div`
    display: grid;
    grid-template-areas:
    grid-template-columns: 240px auto 240px;
    grid-template-rows: 100px auto;
    height: 100vh;
    min-width: 1024px;
    width: 100vw;
    'leftpanel main rightpanel';
    'toppanel toppanel toppanel'
`

I've done a rewrite that addresses this issue. Need to know whether to submit as a PR or publish as a new plugin.
