This bug makes ES6 code unusable if wrapped in a block, such as in Confluence Data Center plugins: https://community.developer.atlassian.com/t/resource-batching-breaks-closure-compiled-es6-code-in-safari/68909 "Different output" is a pretty severe understatement. "Horribly incorrect output" would be more accurate.
