ListView missing in .NET 9 Fluent theme

[antikmozib]

Description

The above screenshots represent the same application and code except that the first one is built with .NET 9 using Fluent theme and the second one is built with .NET 8.

I am wondering if I am missing something here or if it's a bug.

Thank you
