__attribute__ import_module() import_name() not working correctly.

Zig Version

Steps to Reproduce and Observed Behavior

wasmexports.h:

#pragma once

#ifdef __cplusplus
extern "C" {
#endif

void test_function() __attribute__((import_module("test_module"))) __attribute__((import_name("test_function")));

#ifdef __cplusplus
}
#endif

main.zig:

const std = @import("std");

const c = @cImport({
    @cInclude("wasmexports.h");
});

pub fn main() !void {
    c.test_function();
}

inside build.zig:

    const target = b.resolveTargetQuery(.{ .cpu_arch = .wasm32, .os_tag = .freestanding });
    const optimize = std.builtin.OptimizeMode.ReleaseSmall;

wasm module generated:

(module
  (type $type0 (func (param i32)))
  (type $type1 (func))
  (func $import0 (import "env" "test_function") (param i32))
  (memory $memory0 2 2)
  (global $global0 (mut i32) (i32.const 72096))
  (export "memory" (memory $memory0))
  (export "_start" (func $func1))
  (func $func1
    i32.const 0
    call $import0
  )
)

Expected Behavior

We should be seeing "test_module" instead of "env" (func $import0 (import "test_module" "test_function") (param i32))

(module
  (type $type0 (func (param i32)))
  (type $type1 (func))
  (func $import0 (import "test_module" "test_function") (param i32))
  (memory $memory0 2 2)
  (global $global0 (mut i32) (i32.const 72096))
  (export "memory" (memory $memory0))
  (export "_start" (func $func1))
  (func $func1
    i32.const 0
    call $import0
  )
)
