[clangd] Incorrect navigation caused by deducing this

[ymyh]

struct B
{
    template<typename Self>
    auto bar(this Self &&) 
    {
        return 0;
    }

    auto bar2(this B &&)
    {
        return 0;
    }
};

struct A
{
    auto foo()
    {
        return B{};
    }
};

auto baz(int n)
{
    return n;
}

int main()
{
    A a{};
    baz(a.foo().bar());

    A a2{};
    int n  = a2.foo().bar2();
}

incorrect navigation of a.foo and a to baz, a2.foo and a2 to n
