Due to we already set passes: 2 in latest Rspack version (SWC reproduction).

I think the behavior is correct, do we considering enable https://swc.rs/docs/configuration/compilation#jsckeepclassnames or update the snapshot 🤔?

[chenjiahan]

I prefer to keep the class name of Rspack plugins, as some users may use "plugin.constructor.name" to determine a plugin.

I will try the option today.

I just find that Terser mangles class names by default, so using "someClass.constructor.name" is unsafe, I will avoid using it.
