No implementation found for abstract class

[ilev4ik]

For the following sample cpp code, 'Find All Implementations' on A doesn't find class impl only impl2. Btw implementations of A::f are found correctly. The same is observed on Windows.

I also tried to examine index.dex and got it by... (output is attached at index.yaml) ./clangd-indexer --executor=all-TUs --format=yaml compile_commands.json > index.yaml

I suppose it's related to #1325

template <typename... T>
struct Inherit : T...
{

};

struct A
{
    virtual void f() = 0;
};

struct B {};
struct C {};

struct impl: Inherit<A,B,C>
{
    virtual void f() override {};
};

struct impl2 : A
{
    virtual void f() override {};
};

int main()
{
    impl2 i{};
    return 0;
}
