pbjs gives "Error: duplicate name 'Http' in Namespace .google.api"

[cusher]

protobuf.js version: 7.2.6 (cli version: 1.1.2)

With previous versions, including 7.2.5, building many proto files into a single bundle with pbjs/pbts works without issue, e.g.:

node_modules/protobufjs-cli/bin/pbjs -p ../../ $protofiles --keep-case -w commonjs -t json-module -o src/app/proto-reflection.js

With version 7.2.6 installed, this now gives an error:

/projectdir/node_modules/protobufjs-cli/pbjs.js:254
            throw err;
            ^

Using node18 can solve the problem. I just stepped into a pit today...
