In a UXP plugin, there is no consistent way to control the undo/redo stack.

The closest we have is through app.doScript, but this is fraught with many issues.

1. When you run an async UXPScript (most would be, if working with files), the undo mode is ignored.
2. You can run extendscript, but as we are trying to move away from that I would like a uxp supported solution. In general, we have run into issue after issue with app.doScript using extendscript.

Ideally, you would fix item 1 and also some of the surrounding issues with UXP script execution (no way to wait for result? documentation seems to be incorrect as well).
