[data-ogsc] prefixed CSS is discarded on compilation

[viking1304]

How can we reproduce this bug?

Add any [data-ogsc] styling to your _template.scss and it will be discarded on compile.

Write out the HTML (or Inky code) that causes the issue.

[data-ogsc] .link { color: #555 !important; }

What did you expect to happen?

To be able to use [data-ogsc] prefixed elements in CSS.

What happened instead?

[data-ogsc] prefixed elements are completely discarded.

Both {{{{raw}}}} {{{{/raw}}}} and pairs will fail and break the compilation completely, so that doesn't help in this case.
