+// async/await support came with the below specified versions for Chrome,

+// v12 in that it has a GC bug for tagged template literals. We don't currently
+// rely on this functionality so the bug wouldn't effect us, but in order to use
+// browser versions as a measure for ES6 features we need to specify Safari 13
+// for native, non-transpiled template literals. In reality template literals
+// came in Safari 9.1. Safari's async/await support came in Safari 10, so thats
