Can you replace this implementation with these three statements? clang-format
will make it pretty.

base::RunLoop run_loop;

static_cast<StoragePartitionImpl*>(content::BrowserContext::GetDefaultStoragePartition(shell()->web_contents()->GetBrowserContext()))->ClearData(StoragePartition::REMOVE_DATA_MASK_SERVICE_WORKERS,
StoragePartition::QUOTA_MANAGED_STORAGE_MASK_ALL, GURL(),
StoragePartition::OriginMatcherFunction(), base::Time(), base::Time::Max(),
run_loop.QuitClosure());

run_loop.Run();

Done.
