Full Screen Mixers and Workspaces

I have found that using a mixer at fullscreen, it tends to not remember where it was when using a workspace. I was adapting my C7.5 Workspace settings for C8 when I found this behavior: Toggle “fullscreen” on the monitor of choice, press [Alt]+U to update preset, recall preset and the mixer is not at fullscreen, and has relocated elsewhere.

If you ‘stretch’ a mixer window to fill the monitor, it will work with a Workspace preset, which is a workaround for now. If it matters, I am using 3 monitors, with UltraMon as the manager, and the monitor I had the most issue with ws my ‘top’ monitor.
