Not restoring parent Each's key on some conditions

[jettero777]

Description

In EachHandler there are 2 returns without restoring in context parent Each's key.

Code in question:

        $originalEachKey = $context->getParameter(Each::PARAMETER_EACH_KEY); // <== storing parent key

        foreach ($value as $index => $item) {
            if (!is_int($index) && !is_string($index)) {
                return (new Result())->addError($rule->getIncorrectInputKeyMessage(), [ // <== bug, return without restoring parent key
                    'property' => $context->getTranslatedProperty(),
                    'Property' => $context->getCapitalizedTranslatedProperty(),
                    'type' => get_debug_type($index),
                ]);
            }

            $context->setParameter(Each::PARAMETER_EACH_KEY, $index);

            $itemResult = $context->validate($item, $rules);
            if ($itemResult->isValid()) {
                continue;
            }

            foreach ($itemResult->getErrors() as $error) {
                $result->addErrorWithoutPostProcessing(
                    $error->getMessage(),
                    $error->getParameters(),
                    $error->getValuePath() === [] ? [$index] : [$index, ...$error->getValuePath()],
                );
            }

            if ($rule->stopOnError) {
                return $result; // <== bug, return without restoring parent key
            }
        }

        $context->setParameter(Each::PARAMETER_EACH_KEY, $originalEachKey); // <== restoring parent key

        return $result;
