Nested class page not shown in hierarchy

[rnett]

Describe the bug
I have a class like:

sealed class KrosstalkResult{
    data class Success(): KrosstalkResult()
    data class HttpError(): KrosstalkResult()
}

Nested classes are shown properly on the KrosstalkResult page. However, navigating to one of the nested class's pages results in this:

The page is correct, but the navigation sidebar is collapsed instead of showing the location of the class.

Expected behaviour
Nested class pages are present in the navigation sidebar, and their location is shown in the sidebar when they are opened.

This issue is still present in version 1.7.10.

Looks like this has been implemented in #2597, released in 1.7.20. I tried to write a similar reproducer, works fine. Please let me know if I understood it wrong.
