Another Undo issue has come up. A floating dialog with a "Preview" checkbox creates temporary preview art. When the dialog blurs, the temporary art is deleted, but then an Undo by the user will bring it back. I'd like Undo to ignore activity between the dialog's focus and blur, but setting the undo context to silent during this period doesn't change anything. Do I need to do something with the app context? I do appreciate that CORE handles so much of this automatically, especially since I never clearly understood push/pop/suspend/resume app context, but I wonder if this may be an occasion when it's needed. Thanks!
