1. Enable worker debugging.

Is there an easy way to run the same script outside of the worker / on the main thread? Would interested in if this is actually related to worker debugging or is just a breakpoints bug.

I have no idea, sorry.

I'm not sure if this bug is still valid:

 - setting a breakpoint on line 7 never breaks, but the worker has already started by then. This code isn't re-run, right?

 - setting a breakpoint on eg line 18 inside the compute function *does* work perfectly.

Is there some other bug for debugging worker initialization?

There is no other bug for debugging worker initialization. It's something that's on my radar though, so I'll probably open a bug for it some time soon. Feel free to beat me to it if you'd like.

The site linked in the STR is taken over by a 3rd party, but testing on https://afshinm.github.io/50k/ works as expected with bug 1520698 landed.

Please re-open if you find other issues with worker initialization.
