Importing causes possibly undefined symbol on sub element

[marcelotaube-weka]

First I would like to kudos the team, my previous ticket #846 was fixed and i even downloaded the new version and double checked is now working properly. That encourages me a lot to report other problems in the indexing area and hope this plugin becomes even better.

Desktop (please provide environment info):

• OS: MacOs Ventura 13.2.1 (M1 pro apple chip)
• IDE: IntelliJ IDEA 2023.1.1 (Community Edition)
• Plugin Version 1.30.1

D compiler and tools (please provide version numbers):

• dmd: DMD64 D Compiler v2.102.1
• dub: DUB version 1.31.1, built on Feb 15 2023 (installed with brew)
• dcd: v0.15.2

Describe the problem
I'm getting a "Possibly undefined symbol" warning when using importing a struct from a different module and accessing a substruct. This is even if the project compiles and go to definition for the external struct works properly.

Please provide full details to reproduce the problem
Add a file main.d:

module main;
import std.stdio;
import mylib: A;

void main() {
    A.B var;
    writeln("Finished.");
}

Then a second file mylib.d:

module mylib;
struct A {
    struct B {

    }
}
