Subject: vim-patch:9.0.0530: using freed memory when autocmd changes mark
 (#21396)

Problem:    Using freed memory when autocmd changes mark.
Solution:   Copy the mark before editing another buffer.

https://github.com/vim/vim/commit/8ecfa2c56b4992c7f067b92488aa9acea5a454ad

Nvim already copies the mark.
