🤔 Where does the bundle size increase come from? Shouldn't these be wrapped in a process.env.NODE_ENV check. The bundle size checker should take it into account.

[romgrk]

It's all wrapped, here is the output of diff -bur build-master build-this-pr for material-ui: https://gist.github.com/romgrk/98b47d15d498704bd61f89082374c36d. Don't know how the bundle size checker works, can't say anything about that.

The current implementation runs webpack with minifier on a virtual module that imports the package and compares the result with merge base. Interestingly it seems to minify differently. Looks like in the baseline it omits variable declaration in the function body to create a global var, and in this PR it explicitly creates those const in global scope. Quite odd, maybe whitespace related in terser. https://gist.github.com/Janpot/2d3156e4ee4302687e29ae848f230c06

For now it probably makes most sense to not run this plugin on the tests.

[romgrk]

I've disabled the plugin in test. This is ready for review.
