Fixes #3171
StrategyHandler.doneWaiting
throws on the first rejected promise that it encounters. This means that subsequent rejected promises may result in unhandled rejection errors.Promise.allSettled is a natural solution. It does not appear to be supported on all browsers that workbox uses. I tried installing promise.allsettled from NPM but had trouble getting the default import from that module to work correctly with Rollup, and I noticed that the workbox service worker libraries tend to avoid external dependencies in general, so I created a local version instead. I put it under workbox-core's
_private
directory, following the example of other utility code such as Deferred. If I should handle this differently, please let me know.
