Stops style engine from combining CSS selectors by default so that rule order is preserved. Props ramonopoly, rajinsharwar, timdix, costdev, audrasjb, SergeyBiryukov, JeffPaul, mukesh27. Fixes #58811. Built from https://develop.svn.wordpress.org/trunk@56574 git-svn-id: http://core.svn.wordpress.org/trunk@56086 1a063a9b-81f0-0310-95a4-ce76da25c4cd

/**
|
|
* Global public interface method to generate styles from a single style object,
|
|
* e.g. the value of a block's attributes.style object or the top level styles in theme.json.
|
|
*
|
|
* Example usage:
|
|
*
|
|
* $styles = wp_style_engine_get_styles(
|
|
* array(
|
|
* 'color' => array( 'text' => '#cccccc' ),

* )

|
* );

|
* Returns:
|
|
*
|
|
* array(
|
|
* 'css' => 'color: #cccccc',
|
|
* 'declarations' => array( 'color' => '#cccccc' ),

|
|
* When set, the style engine will attempt to store the CSS rules,
|
|
* where a selector is also passed.
|
|
* @type bool $convert_vars_to_classnames Whether to skip converting incoming CSS var patterns,
|
|
* e.g. `var:preset|<PRESET_TYPE>|<PRESET_SLUG>`,
|
|
* to `var( --wp--preset--* )` values. Default false.
|

* @type string $selector Optional. When a selector is passed,
|
|
* the value of `$css` in the return value will comprise
|
|
* a full CSS rule `$selector { ...$css_declarations }`,
|
|
* otherwise, the value will be a concatenated string

* of CSS declarations.
