[Bug]: MSVC ElementsAreArray compilation errors

Describe the issue

Use of ElementsAreArray causes compilation errors on Windows with MSVC.

As far as I can tell, I'm doing exactly what is written in the online documentation.

A minimal example

#include <gtest/gtest.h>
#include <gmock/gmock.h>

class MyTestClass : public testing::Test
{
};

class Foo
{
public:
  virtual void bar(const int values[]) {}
};

class MockFoo : public Foo
{
public:
  MOCK_METHOD(void, bar, (const int[]), (override));

};

TEST_F(MyTestClass, thisShouldWork)
{
  const int values[] = { 123, 45 };

  MockFoo foo;
  EXPECT_CALL(foo, bar(testing::ElementsAreArray(values, 2))).Times(1);

  foo.bar(values);
}

Here is the compiler output

Steps to reproduce the problem

src/main.cpp

#include <gtest/gtest.h>

int main(int argc, char** argv) {
  testing::InitGoogleTest(&argc, argv);

  return RUN_ALL_TESTS();
}

src/foo_test.cpp

#include <gtest/gtest.h>
#include <gmock/gmock.h>

class MyTestClass : public testing::Test
{
};

class Foo
{
public:
  virtual void bar(const int values[]) {}
};

class MockFoo : public Foo
{
public:
  MOCK_METHOD(void, bar, (const int[]), (override));

};

TEST_F(MyTestClass, thisShouldWork)
{
  const int values[] = { 123, 45 };

  MockFoo foo;
  EXPECT_CALL(foo, bar(testing::ElementsAreArray(values, 2))).Times(1);

  foo.bar(values);
}
