Duplicate sourcemap entries w/ serviceworker #12322

lighthouse https://proxx.app/ --preset=experimental -GA

we end up with duplicate entries:

I'm pretty sure this is because of the service-worker, though i'm not 100%. (it's possible some Surma shenanigans w/ comlink are creating two instances of the script.. shrug)

interestingly we get unique scriptIds for these duplicates (reported through Debugger.scriptParsed):

ref #11254
