With typing undone in a paragraph or added text box, its text matches
the page again, so Undo and Redo went to the document. Redo then closed
the box and redid a document change (or nothing), instead of putting the
typing back as the box's own Redo did before. And Shift+Cmd+Z is also
Cmd+Z to the Undo shortcut, so even a Redo the box kept was taken as a
document Undo.
Redo stays with the box while its own history has typing to put back
(the test egui makes when it handles the key), and Shift+Cmd+Z is never
a document Undo.
