All of them fail with the following error: Uncaught exception in Inspector page: ReferenceError: Can't find variable: CodeMirror [TestCombined.js:36658:15] This is because Test.html, even when combined, is trying to load CodeMirror from External/CodeMirror, but CodeMirror was already combined for Main.html. We need to also combine CodeMirror for Test.html. I don't know why this works in Mac.
