Function that scopes a selector with another one. This works a bit like SCSS nesting except the & operator isn’t supported.
Description
$scope = '.a, .b .c';
$selector = '> .x, .y';
$merged = scope_selector( $scope, $selector );
// $merged is '.a > .x, .a .y, .b .c > .x, .b .c .y'Parameters
$scopestringrequired- Selector to scope to.
$selectorstringrequired- Original selector.

* Default layout gap styles will be skipped for themes that do not explicitly opt-in to blockGap with a `true` or `false` value.
