[regression] [worked-in:17.14.14]
Consider the following project structure:

• Project A: References System.Drawing.Common.
• Project B: References A, uses System.Drawing.Bitmap, UseWPF is set to true.
• Project C: References A, uses System.Drawing.Bitmap, UseWPF is set to false.

In this case, Project B cannot find System.Drawing.Bitmap and results in a CS1069 error.
Project C has no issues.

Even when checking with NuGet Package Manager, the package is no longer transitively referenced.

In VS2022 17.14.14, this problem does not occur.

I've attached a sample project where this issue occurs.
