I did more investigation by monkey-patching the `next` package.
`.minify()` resolved without an exception.
It means that `.minify()` is producing an invalid ES code.

So... candidates are

refactor(es/minifier): Remove mutated and mutation_by_call_count (#7890) 
**Description:**

`mutated` can be seen as a combination of `reassigned` and `has_property_mutation`, and `mutation_by_call_count` is simply useless.

fix(es/minifier): Abort seq inliner if var is not fn_local or reassigned (#7804) 
**Description:**

It turns out that the original implementation of `infect`is incomplete
because it cannot cover function param, and the new implementation
introduced in #7772 is redundant because what
[terser](https://github.com/terser/terser/blob/master/lib/compress/tighten-body.js#L909C18-L909C28)
do is basically checking `fn_local`
