Mojo pipe disconnect handler in ServiceWorkerGlobalScope to handle
network pipe disconnections gracefully.

Please format.

File third_party/blink/common/features.cc
Line 2242, Patchset 16 (Latest):BASE_FEATURE(kServiceWorkerRaceNetworkRequestFallbackOnDisconnect,

Please fix this WARNING reported by autoreview issue finding: Consider adding a brief comment here explaining what this feature flag does, similar to the other features in this file.

Line 870, Patchset 16 (Latest): url_loader_factory_remote_.set_disconnect_handler(base::OnceClosure());
Shunya Shishido . unresolved

Please fix this WARNING reported by autoreview issue finding: Nit: `Unbind()` technically clears any registered disconnect handlers, so this line is likely redundant but doesn't hurt.
