/**
|
|
* 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
