Private static class field access breakage with "externalHelpers": true

[strax]

Describe the bug

swc generates erroneous code for private static class field access when the externalHelpers configuration option is enabled.

Running the compiled input code (attached) throws an error originating from @swc/helpers:

TypeError: Private static access of wrong provenance
    at _classCheckPrivateStaticAccess (file:///private/var/folders/c5/w8h8xdfd7xgc946qctjlcs440000gp/T/tmp.lw8GWgIA/node_modules/@swc/helpers/src/_class_check_private_static_access.mjs:3:11)

I presume this line is the culprit as the import is identical to the one above (./_class_check_private_static_access.mjs). The error does not happen when the helpers are inlined, so there must be a difference between the external and inlined helpers.

Input code

class A {
    static #INSTANCE = new A();

    static instance() {
        console.trace("A.instance");
        return A.#INSTANCE;
    }
}
console.info(A.instance())

Config

{
    "jsc": {
        "externalHelpers": true
    }
}
