@U0MKRS1FX I’m puzzled about this too. Did you ever find an answer?

no, never figured it out! “Resolved” it by tweaking advanced optimization to emit non-randomized symbol names with :pseudo-names

Copy that. I imagine there’s a way, perhaps with https://github.com/webpack-contrib/source-map-loader or something akin to it. If I have any success I’ll let you know.
