GTest test does not appear in "Tests" sidebar

When test case starts with a number, test case does not appear in tests output pane:

Minimum example:

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

using namespace testing;

class foo : public ::testing::Test
{
protected:
void SetUp() override {}
void TearDown() override {}
};

TEST_F(foo, 1bar)

I have been looking in QtCreator code to see what is wrong, but I got stuck, and I do not know how to continue. It appears that in gtestvisitor.cc on line 48 is checking if symbol argumentCount() is 2. Seems like TEST_F is parsed here as function, and seems like this code checks that this function has 2 arguments. However, since this is not function, I am guessing that during parse its arguments get discarded because one of them starts with number, and argumentCount() on line 48 returns 0, so gtestvisitor skips the test case, and does not put it in "Tests" sidebar.
