>>> STR_1: 1. Open url https://dl.dropboxusercontent.com/s/8etgnqibearj1ii/2016.08.16%20sourcemap%20404.html 2. Open debugger 3. Switch to script "advanced.js" AR: Script shows HTML of dropbox's 404 error page ER: Either X or Y X) Debugger should show something I can debug in script "advanced.js" Y) Debugger shouldn't load all that bunch of scripts and allow me prettify and debug original file STR_2: (further experiments) 1. Open url https://dl.dropboxusercontent.com/s/8etgnqibearj1ii/2016.08.16%20sourcemap%20404.html 2. Open debugger 3. Black box scripts "react15.js", "jquery.min.js" 4. Set breakpoint on "resize" event 5. Resize the page [debugger will stop] 6. Press "Step in" several times AR: Debugger switches to some scripts, each of them shows HTML of dropbox's 404 error page. So, it doesn't show me sources, but it looks like debugging is in progress. ER: Either X or Y X) Debugger should show some sensible code in each script Y) Debugger shouldn't load all that bunch of scripts and allow me prettify and debug original file

The original test case didn't work for me; I downloaded it and edited various URLs, and then it worked ok. I'm not 100% sure I didn't change the behavior in some test-affecting way.

The tests don't work and I believe there's no way to contact Arni any more, so I'm closing this.
