I want to be able to save/load debugger state

Live in-browser debugging often requires trial and error. The current DevTools don't allow tracing backwards, so sometimes you have to reproduce the problematic scenario over and over, which could be tricky, especially if it's a flaky race condition. It would be great to have a possibility to dump the current debugger state to a file, so you can restore it later and start from the same place.

Note: I previously submitted a "broader" want, but this is perhaps the most important aspect of that.
