/**
* Use a private PostCSS API to remove the "clean" flag from the entire AST.
* This is done because running process() on the AST will set the "clean"
* flag on all nodes, which we don't want.
*
* This causes downstream plugins using the visitor API to be skipped.
*
* This is guarded because the PostCSS API is not public
* and may change in future versions of PostCSS.
*
* See https://github.com/postcss/postcss/issues/1712 for more details
