Steps to reproduce

This looks to be a bug with setTImeout/the event queue. It seems to be very intermittent but the gist ss reported at defunctzombie/node-process#56 is that it looks like it’s possible to add a setTimeout run synchronous code and then call clearTimeout but have the timeout callback called anyway. If I had to guess my suspicion would be that certain dom functions may block the thread without blocking the event loop (like this bug in firefox)

    • Thanks for your patience while I ran some tests on this item. I haven’t been able to get this to repro so far. I added in an alert that will fire if false is ever encountered and still have yet to see that happen.

      Do you think you can add in a way to repro this more effectively? I modified the one you provided to Mozilla but so far have been unsuccessful in replicating the problem in Edge.

      I was using this repro URL:

      All the best,

    • I was never able to reproduce myself, but I opened I asked the people who opened the bug to see if they could help out

    • Okay, thank you. Obviously, as they stated it is hard to repro, but so far - no luck on my end in a single instance of repro.
