Nvim uses a floating window for the autocmd window, but in certain situations, it can be made non-floating (`:wincmd J`), which can cause issues due to the previous setup and cleanup logic for a non-floating aucmd_win being removed from aucmd_prepbuf and aucmd_restbuf. This can cause glitchiness and crashes due to the aucmd_win's frame being invalid after closing its tabpage, for example. Ensure aucmd_win cannot be made non-floating. The only place this happens is in win_split_ins if new_wp != NULL.
