Undo shortcut triggers paging between projects

Undo undo change change

When multiple Glyphs windows are open, Glyphs 3 activates another window when selecting the undo change menu-item or pressing ⌘Z.

Problem with undo command in full screen mode — Glyphs 3

Let’s say I have 1 Glyphs 3 project open in full screen and 1 other Glyphs 3 project that is not in full screen. If I undo an action in the full-screen window, it will jump to the project that is not in full screen. If I press undo six times, it will bounce back and forth six times. I know it sounds kind of crazy, but I would love a fix for this. macOS Catalina
