parseIncludes ignores sparse field set on included data

[nivv]

I'm trying to figure out how to specify which fields to select when including a resource. But I can't get it to work. I've been looking through the Manager-class and I found this:

fractal/src/Manager.php

Lines 194 to 214 in a38f0b7

	// Matches multiple instances of 'something(foo|bar|baz)' in the string
	// I guess it ignores : so you could use anything, but probably don't do that
	preg_match_all('/([\w]+)(\(([^\)]+)\))?/', $allModifiersStr, $allModifiersArr);
	// [0] is full matched strings...
	$modifierCount = count($allModifiersArr[0]);
	$modifierArr = [];
	for ($modifierIt = 0; $modifierIt < $modifierCount; $modifierIt++) {
	// [1] is the modifier
	$modifierName = $allModifiersArr[1][$modifierIt];
	// and [3] is delimited params
	$modifierParamStr = $allModifiersArr[3][$modifierIt];
	// Make modifier array key with an array of params as the value
	$modifierArr[$modifierName] = explode($this->paramDelimiter, $modifierParamStr);
	}
	$this->includeParams[$includeName] = $modifierArr;

Request I'm sending

GET /api-endpoint/producers?include=owner(id|name)

I've also tried the below formats

GET /api-endpoint/producers?include=owner:fields(id|name)

GET /api-endpoint/producers?include=owner:field(id|name)

I found that syntax from another issue: #386

How is it supposed to work?
