git clone --single-branch -b hugo-forum-topic-57211 https://github.com/jmooring/hugo-testing hugo-forum-topic-57211
cd hugo-forum-topic-57211
hugo mod npm pack
npm install
hugo

Hugo emits this warning:

WARN npm dependencies are out of sync, please run "hugo mod npm pack" (you may also want to run "npm install" after that)

Now pack again:

hugo mod npm pack
hugo

No warning.

Tested with v0.162.0, but I suspect this has been there for a bit.
