FieldtypeRepeaterPorter::importConfigData() does not apply fields’ context data

[romaincazier]

After creating a new Repeater field, I’m adding fields like this:

$repeaterField = $fields->newField([
	"type" => "FieldtypeRepeater",
	"name" => "repeater",
	"label" => "My repeater field"
]);
$repeaterField->save();
$repeaterField->type->importConfigData($field, [
	"field1" => ["columnWidth" => 50],
	"field2" => ["columnWidth" => 50]
]);

However the fields’ context data is not applied. After a quick look at the FieldtypeRepeaterPorter class and a test, it looks like the fieldgroup needs to be saved first before the context, so you would need to replace lines 100-107 by:

if($template) {
	if($saveFieldgroup) {
		$template->fieldgroup->save();
	}
	if($saveFieldgroupContext) {
		$template->fieldgroup->saveContext();
	}
}

Also a quick question: is repeaterFields ever used? It looks like it doesn't make any difference to have it or not in the config data
