[EPIC] Collection of Undo issues

This is the Epic to collect issues regarding Undo functionality. Particular issues may be resolved implicitly as others get fixed as they're likely to be interconnected. So this Epic's purpose is mainly for developers and contributors to keep track of them and as a single-point of view.

If you have an issue or feature request regarding this, pls do not report or coment here, instead you support developers best this way:
Open up a new issue (after you made sure it has not reported already) and link to this issue by adding [#303762] to that issue (either in a comment or the issue description).
