What
Frames of buffer-compiled modules can carry a name the SDK cannot predict: Firefox derives it from the compile call site, and V8 hashes the content of modules at or below 16383 bytes. Such frames now resolve to the registered module when exactly one distinct module was compiled from raw bytes.
Why
Without this, non-streaming symbolication misses Firefox entirely and small modules on V8.
