Starting a few hours ago, mwext-php70-phan-docker fails with the following error on all GrowthExperiments patches
includes/HelpPanel/QuestionRecord.php:7 PhanRedefinedInheritedInterface \GrowthExperiments\HelpPanel\QuestionRecord inherits abstract Interface \JsonSerializable declared at internal:0 which is also declared at ../../vendor/jakub-onderka/php-parallel-lint/src/JsonSerializable.php:4. This may lead to confusing errors.
This is currently blocking all merges.
