Will add it to my backlog while I'm working on pointer events 👀 (but feel free to assign yourself if anyone else is interested).

Looking at the stack again, I think Masayuki may have an idea since I haven't touched HTMLEditRules:

Ah, yeah, the given point can be outdated.
https://searchfox.org/mozilla-central/rev/c24ecdc6f5025ea7e60d0691673de030bd5bf411/editor/libeditor/HTMLEditSubActionHandler.cpp#1540-1541,1560,1588
afterBRElement is fixed before calling MoveNodeWithTransaction, but it and event listeners may change the DOM tree. Perhaps, it tried to put caret at the offset of afterBRElement. So, using AutoEditorDOMPointChildInvalidator in the block must fix the bug.
