After updating to `9.0.26195.12303`, I find my `Eto.Forms.ListBox` list item images are no longer shown:

v8

v9

These screenshots show the same plugin binary running in v8 and v9 on win11. The `ListBox` has its `DataStore` set to an `ObservableCollection<NodeListItem>` where `NodeListItem` has a public `Image` property of type `Eto.Drawing.Image`.

I cannot guarantee this issue first appeared in this exact beta build, but I believe so.

Hey @jdhill, I tried to reproduce this with Bella installed but I can’t figure out how to show that particular panel (it does not show up in the panels list). Could you give the [latest dujour build](https://files.mcneel.com/dujour/exe/20260811/rhino_9.0.26223.09513.exe) a try and let me know if it resolves the issue for you?
