.NET version

.NET 9.0.2

Did it work in .NET Framework?

No

Did it work in any of the earlier releases of .NET Core or .NET 5+?

No. Issue #6380 claims this was fixed in .NET 7. However, the issue was not fixed, and the same sample app from that issue continues to reproduce the issue.

Issue description

Icons on TreeView nodes stay small when using high DPI.

Steps to reproduce

Download the repro from issue #6380: TreeViewImagesBug.zip. Update the TFM to .NET 9 and run it.

Note that the tree view icons are the same size at 200% and 100% DPI. (The below screenshots should appear approximately to-scale.)
